LEED by exampleAt the most recent BICSI Conference, held the second week of September in Las Vegas, I enjoyed the presentation delivered by Bill Weekes, a Registered Communications Distribution Design-er with Fancom Network Integrators (www.fancomni.com). He provided fi rsthand, practical information on a

topic that might not be extremely familiar to many in the cabling in-dustry—the Unit-ed States Green Building Council’s Leadership in En-ergy and Environ-

mental Design (LEED) program.Weekes was not familiar with

LEED when he fi rst got involved in it, as he freely admitted during his presentation. In fact, if I remember his story correctly, he was commit-ted to carrying out a certain projectbefore learning it would be LEED-certifi ed, so had to take a crash course in the topic to go along with on-the-job training. Th at’s where much of the value in his BICSI presentation comes from. Here was an RCDD speaking to other RCDDs about what it’s reallygoing to mean to them when they get involved in a project that is gunning for LEED certifi cation.

It doesn’t matter where a project’s tradespeople stand on the sociopo-litical spectrum when it comes toenvironmental causes; if the project is aiming for LEED certifi cation, and these trades want to be paid, they’ll comply with the building owner’s demands for enviro-friendly materi-als, processes, and systems. So, while some who saw Weekes present last month might scoff at LEED’s inten-

tions, it would be in their best inter-est to acquire the ability to bid on and carry out LEED-based contracts.

Even so, I couldn’t shake the ironyof my own actions immediately fol-lowing that presentation. I got out of my chair, grabbed my empty waterbottle, and looked for something I knew I wouldn’t fi nd—a recycle bin. So, I threw the bottle in the trash bar-rel, on top of paper products and alu-minum cans that also occupied it.

A few years ago, at a diff erent con-ference in Las Vegas, I wanted todeposit my empty aluminum caninto a recycle bin, so I asked a member of the convention center’smaintenance staff where I could fi nd one. Based on the look she gave me, I initially believed she did not under-stand English. In fact, she spoke the language fl uently as far as I could tell; it was the notion of a recycle bin that put such a perplexed look on her face. Th at’s when I realized the city’s punchline of a motto was true on sev-eral levels, and in this case could be changed to, “What happens here, gets landfi lled here.”

Expecting a place known as Sin City to provide a positive example of environmental stewardship is unre-alistic. But, as Weekes’ presentation pointed out, when those controlling the purse strings are thinking envi-ronmentally, the dynamic changes.

I’ll be interested to hear more about our industry’s take on LEED.

Most of us are fa-miliar with the installation specifi cations that have been written for unshielded twisted-pair (UTP) cabling sys-tems. Th ese specifi cations include such topics as pair untwist, bend radius, and pulling tension. And while we are familiar with these standard requirements, many—especially those new to the trade—may wonder why such handling restrictions exist.

What happens if the specifi cations are not followedexactly? And why are the specifi cations more critical, and more restrictive, when transmitting higher data rates?

Th e key point of this entire article is: installation quality and correctness. Th ey are vital, and they areentirely up to you.

Let’s fi rst consider that the twisted pair was de-signed several decades ago to transmit a voice signal at 4,000 Hz. Over the past 15 to 20 years, to accom-modate computer and data networking traffi c, thedesign has been upgraded to allow transmissionrates to go from 4,000 bits/sec to millions and poten-tially billions of bits/second. And, of course, installation methods have had to be upgraded accordingly.

The lexicon of data transmissionTh roughout this article, I will use the terms “frequency,”

“hertz,” “megahertz,” “megabits,” “gigabits.” Let’sensure we know what they all mean.

Hertz, or cycles per second, is an analog term. A hertz is one electrical energy cycle, above and below the cen-ter line, occurring in one second of time. In digital terminology, we use the term “bit,” which is one elec-trical energy pulse, above or below the center line or a combination of both, occurring in one second of time.Multiple hertz, or bits, can occur—four, forty, thousands, even millions—in a single second.

Any information that is transmitted involves the use of frequencies or bits, even including 60-hertz alternat-ing current (AC) power. Information includes voice, mu-sic, radio, data, video, television, or even light, as in fi ber optics. Th e more information we have to transmit, the

more hertz, or bits, it takes to do so, and the more com-plex the technology required to transmit it.

In the computer and data business, all of the informa-tion seen on the computer screen is converted to electri-cal, or ones and zeros—a bit represented by a one and the absence of a bit represented by a zero. But there are other types of information sources, such as data transducers, industrial devices, and cameras that are frequency-based. In most of these cases, the frequencies are converted to bits before they are transmitted.

Oft en, there are signifi cant diff erences between hertz and bits concerning how they are processed and conveyinformation; but considering our discussion on

Although the relationship between hertz and bits is not always 1:1, there is a correspondence between the two. Shown on the left is a cycle of 4 hertz/second; on the right is a cycle of 4 bits/second.

cabling-installation specifi cations and practices, we can deal with the two terms interchangeably.

Another term we will use when talking about cable perfor-mance is signal-to-noise ratio, or SNR. Th is is simply a num-ber expressing the diff erence between the power level of the information signal in a circuit, and the power level of the noise, hum, static, crosstalk, or other undesired interfering signals that are also in the circuit. SNR is expressed as a ratio; thelarger the number, the better the circuit quality.

Directly related to SNR is bit error rate (BER). As the bit power level gets down close to the noise level, the receiver may have diffi culty deciding if there is a one or a zero at a givenperiod of time. If the receiver makes a mistake and readsa one instead of a zero, or vice versa, we have a bit error.

Twisted path of twisted pairTh e twisted pair is a rather high-tech precision piece of hard-ware. Two areas of concern and how they relate to each other are: 1) the physical construction of the cable, and 2) the elec-trical characteristics of signal transmission.

Th e cable’s physical construction incorporates four signifi -cant characteristics:1. Th e diameter of the conductor and conductor material;2. Th e type of insulating material along with its density and

thickness;3. Th e spacing between the insulated conductors of the pair as

well as the spacing between the four pairs in the cable;4. Th e twist rate, or number of twists per inch, of the two con-

ductors of a pair—but also the relative twist rate of each of the four pairs in the cable, each pair in a given cable having a diff erent twist rate.Th e electrical characteristics of signal transmission include

the following items, each of which is complex and requiresdetailed explanation:

Resistance (R) is the resistance of the conductor to the pas-sage of electric current. Resistance is constant along the con-ductor, controlled primarily by the size of the wire (the larger the wire, the less resistance it has) and the type of material (copper being the almost universal choice), and is measured in ohms(Ω). Another contributing factor to overall resistance is the type, thickness, and density of the insulation. Collectively,these resistance factors result in less signal received at thereceiver, a poorer SNR, and a higher bit error rate.

Leakage or conductance (G) is the conductance of the insu-lation on each conductor to the passage of current leaking out to the adjacent conductor of the pair, or to the other pairs, or to ground. It is almost negligible in its electrical eff ect on the circuit, but it is there nonetheless and needs to be mentioned. Being very high in value, it is measured in megohms, or mil-lions of ohms. It combines with resistance to weaken the sig-nal along the pair, and is also constant along the conductor as well as controlled by the type of insulating material, its thick-ness, and its density.

Inductance (L) and its current-fl ow-inhibiting eff ect, induc-tive resistance (XL), are also signifi cant characteristics. Induc-tance is the magnetic eff ect of alternating current signal fl ow in a conductor. It opposes the applied signal voltage, which in turn reduces the signal current fl ow, which then results in less signal into the receiver, and then to a poor SNR and poorer BER. Inductance is also constant along the conductor. But in this case, the higher the signal frequency or bit rate, the higher the current-inhibiting eff ect. Although inductance is inherent in any conductor, it is signifi cantly increased when the con-ductor is curved or formed into a coil. Th e sharper the curve, or more rotations in a coil, or the smaller the diameter of the coil, the greater the inductance. Th ese factors relate problems resulting from tight bends or kinks in the cabling.

Capacitance (C)—and its signal coupling eff ect, capacitive reactance (XC)—is the coupling eff ect of alternating current signal fl ow between electrical conductors and components. It allows signal coupling between the wires of a pair andbetween pairs. Th e common eff ect is crosstalk. Capacitance is inherent in a conductor or component. It is also increased by closer spacing or by a larger-size conductor or component. Th ese factors relate to problems resulting from crushing, twist-ing, and bends that bring the conductors closer together.

Impedance (Z) is a frequently discussed characteristic.Expressed in ohms (Ω), it is a mathematical result of com-bining the values of resistance, inductive reactance, andcapacitive reactance. It is also a design value of all majorcircuit components, such as transmitter, cable pair, andreceiver. In designing and installing a circuit, try to keep all com-ponents and connections as close as possible to the design imped-ance, which in the case of network circuits is 100 Ω. In contrast, older data and telephone circuits were 600 and 900 Ω,

Signal-to-noise ratio (SNR) is a critical electrical performance parameter, and shown here are examples of good and poor SNR in analog trans-mission (left) as well as digital transmission (right).

Excess pulling tension

Correct form and spacing Elongation with reduced density and diameter


respectively. From a practical viewpoint, when installationerrors occur, such as tight bends and tie wraps, damagedcable or components, or poor joints, the component and over-all design impedance is changed. And when all circuit com-ponents are not working at 100 Ω, one or more impedance mismatches occur.

Th ese cause, at the location of the mismatch, signal refl ec-tions back toward the transmitter and a reduction in signal power going to the receiver. Th e worse the cumulative mis-matches, the less the signal that is actually sent to the receiver,resulting in poorer SNR or BER. Th e signal refl ections are called return loss, and are expressed in dB. Th e higher the dB number, the fewer installation problems and the better

the circuit. All of these characteristics workingtogether (or, in another sense, working againstone another) determine the electrical perfor-mance of the UTP cable. Th ey collectively aff ect the smooth fl ow of current, which makes up the data signal, through the cable.

High-tech cables are designed and constructedvery precisely. The dimensions and com-position of the conductors and insu-lation are carefully controlled. We are

speaking of dimension tolerances of thousands-of-an-inch and material compositions in parts-per-million. Th is isalso related to the relative placement of each conductor andits placement in the cable. So, any physical factor that distorts or aff ects these tolerances, even ever-so-slightly, changes theinductive and capacitive design parameters, which in turn aff ect the electrical reactive values, which then aff ects the fl ow of signal current through the cable. In these cases, impedancemismatches and refl ections cause crosstalk, signal loss, noise, and then bit errors.

Let’s look at some of the installation specifi cations and see how even small mechanical distortions can aff ect transmis-sion performance.

• Excess pulling tension—One action that can adversely aff ect signal trans-mission is exerting too much pulling tension or, stated diff erently, stretching the cable. Th e Telecommunications In-dustry Association sets the maximumpulling tension at 25 pounds. When install-ers exceed that limit, it results in elonga-tion of conductors and insulation, which in turn reduces the diameter and densi-ty of those components (the insulation more so than the conductor). Exerting too much pulling tension also lengthens the twist rate of not only each individual pair but also the relative rate between each of the four pairs. In both cases, it wouldlikely occur in isolated sec-tions, not the total cable length, de-pending on the nature of the pull.

• Bend-radius violations—Violating mi-imum bend-radius limits by bending the cable too tightly or even kinking also has deleterious eff ects on signal transmission. Current specifi cations call for a minimum bend radius of four times the cable diam-eter in horizontal applications. Oft en, you will see two values: static and dynamic. Th e static value is the minimum bending

Excess pulling tension elongates a twisted-pair cable’s conductors and insulation which, as this exaggerated-for-effect illustration shows, reduces the diameter of both components.

radius of the cable aft er it is positioned or placed in its permanent loca-tion, with no further movement. Th e dynamic value is the minimum bendradius to be observed when the cableis being pulled and placed into posi-tion. Th is is the larger of the two num-bers because of the added stress being placed on the cable as it is being in-stalled. Ignoring the bendradius specifi cation results in stretching or elongating the pair twist on the outeredge of the cable, and compression or buckling of the smooth lay and pair twist on the inner edge. Th e normal concern is for cable in trays and race-ways in long horizontal runs. Th e worst problem exists when excess slack is pushed back into a pullbox or outlet box, where very tight bends or even kinking could occur. Kink-ing, which can occur even when pull-ing the cable out of its supply box, is, of course, a severe case; once done, a kink really cannot be completelyundone. In any case, a kink produces a severe inductive-reactance spike. It also likely will cause the conductors to be pushed closer together.

• Cinching too tightly—Fastening ca-bles too tightly with tie wraps, clamps, or staples is a specifi cation violation. Generally, specifi cations are rath-er subjective about this matter, but the overall creed is not to cinch thecables so tightly that the cable can-not be gently pulled under the fas-tener, or so that the tie wrap cannot be slid along the bundle. Failing to adhere to this guideline can result in crushing the cable, thereby in-creasing the density and reducing the diameter of the insulation sur-rounding the conductor, as well as the cable sheath. Additionally,it reduces the spacing betweenthe conductors of a pair and the spacing among the four pairs of thecable. Finally, in extreme cases (as with a staple), the conductors can be bent or kinked. ➤

• Insulation, jacket removal—Specifi cations also address the untwisting of the twisted pairs prior to termination. Specif-ically, installers are told to untwist as little as possible, but in no case exceed ½-inch or extend beyond the rear of the con-nector. And although it is unavoidable at the point of connec-torization or punchdown, this action, even for a very short distance, untwists the conductors of the pair and sometimes increases the spacing between them. Th is concern is also true for the four pairs in the cable. Depending on the type of connector block, specifi cations vary concerning how much insulation may be removed from the conductor, as well as how much sheath may be removed from the cable. Generally,specifi cations say to remove only as much as is absolutely necessary. Th e ideal case is with punchdown blocks, where no insulation is cut back at all. Disregarding the specifi ca-tions about insulation removal will cause a small change in the cable’s impedance, because the insulation on a con-ductor is one factor that determines impedance. Addition-ally, the sheath is the key factor in holding the four pairs in place and in relative position to one another. So, removing the sheath also removes this stabilizing factor.

• Eff ects on delay skew—Even delay skew, an electrical char-acteristic most closely associated with the material used to insulate conductors, is subject to variation, depending oninstallation technique. Workmanship involves terminat-ing the pairs of the cable in such a way that each pair is cut to length in the connector or terminal block. Mechanically,this avoids having extra-length pairs bunched up in theconnecting area. In so doing, however, each of the four pairs ends up having a slightly diff erent length. Specifi cations call for a 45-nanosecond maximum delay skew, among the four cable pairs, along a 100-meter span. Th at is the diff erence in time, among the four pairs, one to another, for the signals to prop-agate through the cable from the transmitter to the receiver. Erroneous installation methods can have a detrimental eff ect. Very high data-rate signals that are divided into four parts must be recombined in the proper order, or sequence, at the

receiver so that the original signal can be properly detectedand decoded. If there is too much diff erence in the rela-tive data length of each of the four pairs, some bits will bedelayed too much and get recombined out of their proper order, with resultant bit errors. Th e specifi cation allows for diff erences in propagation delays due to the diff erent twist rates on each of the four pairs; however, when cutting the four pairs to the same length, extra care must be taken so that the retained slack does not become kinked nor violate the minimum bend radius specifi cation.

• Cable combing—Combing the cable installa-tion—installing or laying the cables in a trayneatly, side by side—is a practice not addressed in specifi -cations yet, but may soon be. It is, without question, a tech-nical-performance concern. In long runs of several cables, it is customary to install the runs in an orderly, straight, and side-by-side manner. Th is technique provides a very neat and professional appearance; however, particularly atvery high data rates, it also allows the inductive reactance coupling of electric fi elds surrounding the conductors

to more easily combine and build up, and the capacitivereactance coupling between the conductors to further mini-mize. Th e main concern is not totally between the four pairs in a given cable, but the cable-to-cable coupling directlyaff ecting alien crosstalk. By using a random lay, the cables are constantly changing their relative spacing and crossover position. Th is reduces the chances for a long exposure toinductive and capacitive coupling. In fact, coupling fi elds can actually experience some cancellation as they wander

While aesthetically pleasing, neatly combed bundles are proving detri-mental to cable performance. Randomly laid cables may not look pretty, but yield better results.

Cinching cable bundles too tightly by any means may kink or crush conductors, adversely affecting their performance.

in a random fashion along the cable tray or rack.Even if you have followed the installation specifi cations per-

fectly, it is more diffi cult to get good BERs at high data rates than at lower rates. (Please note that the following formulas only illustrate relationships, and should not be used for actualcircuit calculations). Critical factors are inductive and capac-itive reactance.

Remember that inductance is constant along the conduc-tor; however, the higher the signal data rate, or frequency,

the greater the reactance, or current-inhibiting eff ect, or induc-tive reactance XL. As the data rate, frequency, or inductance increases, XL also increases.

Th is can be expressed mathematically with the following for-mula: XL=2ΠfL. 2Π is a constant with a value of 6.28; f is the data rate or frequency; and L is the inductance of the pair or other component at a given point in the circuit.

XL exists even in all good circuits, but its eff ect is made worse by problems with too-tight bends, kinks and, to some extent,

with staples and tie wraps.Capacitance is also constant along the

conductors. But in this case, the capacitive resistance, XC, in contrast to XL, decreases as the signal data rate increases. So, with a smaller XC, or opposing eff ect to signal coupling, crosstalk can increase as the da-ta rate, or frequency, increases.

Th is also can be expressed: XC = 1/2ΠfC. 2Π is the constant 6.28; f is the data rate or frequency; and C is the capacitance be-tween the pairs or other components at a given point in the circuit.

Like XL, XC is a factor in well-estab-lished circuits, but its effect can eas-ily be made worse by problems with crushing, twisting, bends that bring the conductors closer together, and longinstallation runs of combed cable.

Th e resistance eff ect also increases with higher data rates, although it is not quite as contributory as is inductive reactance. Th e increasing eff ect is due to the way the higher-frequency energy propagates along a conductor—a condition called skin eff ect. Also of importance is the chemical com-position of the insulating materials, which aff ects the impedance characteristic of an insulated conductor. Higher frequen-cies are attenuated more so than the lower ones. Th is eff ect is related to the insulation dielectric constant. (Please note that when discussing signal transmission, most spec-ifi cations and other literature refer to resis-tance factor as attenuation.)

Quality controlInstallation quality and correctness leaddirectly to maximum signal-to-noise ratios and minimum bit errors. In that sense, sys-tem performance is up to you—the install-ers and operators of cabling systems.

installation

Communications net-works never go slower, never get simpler, and never stay the same. Likewise, certifi ca-tion testing for fi ber-optic cabling has also changed.

New test equipment and enhanced testing regiments help ensure that cabling can support the new demands placed on networks. Born from legacy test equipment for telecommunications networks, some of these fi ber testers were diffi cult to use. But a new generation offi ber test equipment is designed to make it easy to certifyfi ber to the latest standards.

Not long ago, the state-of-the-art for fi ber-opticcabling was the 100Base-FX standard from the Institute of Electrical and Electronics Engineers (IEEE; www.ieee.org), which supported a bit rate of 100 Mbits/sec over a channel with an attenuation of 11 decibels (dB). Today, for IEEE 10GBase-S to support a transmission rate 100x higher than 100Base-FX, the transmission channel must attenuate the light by no more than 2.6 dB. It is this tight-ening of requirements for the physical media that repre-sents a challenge for all components used to build and test a transmission path.

A standards-compliant connector can contribute up to 0.75 dB (0.5 dB typical) to the total loss. Th is would mean that if you patch two fi ber segments together, there would be a total of four connectors, which could—even though each individual segment is compliant—result in worst-case loss of 3 dB (4 x 0.75). Th is exceeds the loss budget left for the entire link, and with a negative allow-ance left for the fi ber itself.

More than a loss measurementIt is here where new test methods are required. Installers who work with optical fi ber are, no doubt, familiar with the optical loss test set (OLTS). Performing a loss-length

test with an OLTS is an essential part of fi ber installa-tion. Every link needs to be tested to ensure it is within the loss limits. But an OLTS will only show if a link has passed or failed. If it fails, the OLTS will not show you why it failed, or where.

For these answers, an optical time-domain refl ec-tometer (OTDR) comes into play. Using an OTDR need not be complicated or confusing. Understanding a fewbasic concepts will make OTDR use as straightforward as using a copper certifi cation tool.

Testing fi ber links as defi ned by national and inter-national standards, such as the TIA/EIA-568-A and ISO-11801 specifi cations, includes the use of an OLTS. Recently updated standards that focus on test methods for installed fi ber links, such as ISO-14763-3 and TIA TSB-140, now recommend the complementary use of an OTDR. Th ese new standards add the use of an OTDR to verify not just that the link has passed, but to ensure the quality of each installed component on the link. ➤

Using an OTDR:How to keep it simple

Not just for use in public networks, the optical time-domain reflectometer no longer has to be an intimidating tool.

CHRISTIAN SCHILLAB CHRISTIAN SCHILLAB is segment product manager with Fluke is segment product manager with Fluke Networks, Europe (www.fl ukenetworks.com).Networks, Europe (www.fl ukenetworks.com).

According to ISO-14763-3, the correct setup for an OTDR uses both launch and receive (tail) cords, but no measurement device on the far end. The gaps in red show the loss at each connector.

Two levels of testing are defi ned in these updated stan-dards: Basic (or Tier 1) testing uses an OLTS. Extended(or Tier 2) testing involves the use of an OTDR and an OLTS.

The following example helps demonstrate how anextended test regime can help to ensure consistentquality during installation. Assume that the first con-nector in a 2-connector, 100-meter fi ber link performsextremely well, while the second connector is poorly installed or contaminated. In such a circumstance, the measurement

with an OLTS may show that the link passed by a slim mar-gin of 0.02 dB, but does not identify the second connector as a bottleneck (noted in bold).

Identifying bottlenecks is the strength of an OTDR, which sends a pulse of light into fi ber and measures the lightrefl ected back at each component as the light lost at that compo-nent. Th e same is true for backscattered light along the length of the fi ber itself.

Little setup requiredAn OTDR can produce accurate, highly detailed measurements, if the correct setup and necessary accessories are employed.Recent versions of standards like ISO-14763-3 make an attempt to specify all necessary elements for a correct measurement with an OTDR, eliminating common sources of measurement error, including:• Specifi cations for launch and receive fi bers;• Correct use of launch and receive fi bers;• Instructions detailing how to position the cursor for the cor-

rect reading of link, component, and segment attenuation;• List of conditions under which it is vital to measure each

fi ber in both directions.You may view these setup requirements as overly complex,

which may explain why many consider the OTDR to be a tool for experts only. Th is is also why installers and contractors may choose not to bid on projects that require an OTDR, or subcontract this work to a company specializing in fi ber. Such

thinkingis in contrast to the certifi cation of twist-ed-pair copper cabling systems, where aft er setting the correct standard, a single press of the autotestbutton does everything.

Fortunately, the actual use of the OTDR is not as challenging as it appears. Making sure that test leads, launch fi bers, andreceive fi bers are in a crisp

condition, and are clean and correctly connected, will always be your responsibility. But the remainder of the setup steps can be taken care of by the instrument. Newer OTDRs willcreate an image of the proper setup confi guration. Youmerely need to make connections and have the instrument

“learn” the launch and receive fi bers.Aft er this step, the tes-

ter will be ready to certifylinks and all included components for their compliance. Often, a project-specifi c standard, which is derived from the manufacturer’s data sheet or reference imple-mentation, will be used to set these limits.

Pass, fail, or squeak byWhen the tester is proper-ly confi gured, the tests are as simple as copper certi-

fi cation. Th e most com-mon situation should be that the link passes, and a “pass” indication on the summary screen will in-dicate the tester evaluat-ed all elements of the link.Results are stored for laterreporting. The instru-ment also automatically subtracts the contribution of the launch and receivefi bers from the total link, showing only the total overall loss.

While this example is suffi cient information for a passing link, you

The OTDR will learn the launch and receive fi bers, thereby allowing it to

subtract their loss contribu-tion from the overall link measurement.

This is a report of a link that failed even though the overall loss was below the allowable limit. The reason for failure was the single largest event of 0.92 dB, which was outside the design specifi ca-tion. Standard loss-length tests would not identify this single event. ➤

will need to dig deeper and get more-detailed information if the link (or parts of it) failed the specifi ed limits.

You can see, forexample, that the loss may be 1.07 dB andwithin the limits, but a single bottleneck con-tributes 0.92 dB to the overall loss.

A fully automatic OTDR automates the test to the same level as a copper fi eld tester, using internal expert diagnostics to inter-pret all the information from the OTDR test, and presents the results in a simple,easy-to-understand table.

Everyone’s an expertMany react negatively when they hear the term “OTDR.” But rather than thinking of words such as “complicated” and “ex-pensive,” you could think phrases such as “just like my cop-per tester,” and “a chance to grow my business.” Installing and testing fi ber may be new to some contractors, but the right equipment can make the job easier.

An expert reader of this article will recognize the trace shown in the illustration above. Th e launch and receive events are clearly visible to the left and to the right of the link.

Also visible is the 0.92-dB receive event at 49.5 meters. Butthe key to today’s OTDRs is that you don’t have to be anexpert. If you are an installer of copper cabling systems, an OTDR will off er you three qualities:1. Expert diagnostics that make the OTDR work much like

your familiar copper certifi cation tool;2. A means of bidding on more jobs, growing your business

and increasing profi ts;3. Th e ability to move your knowledge of copper systems

into a new area and become a fi ber expert.

technology

The process of fusion splicing has been around for several decades, and in out-side plant (OSP) applications, it remains the most common and trusted method for permanently fusing together the ends of two optical fi bers to realize a specifi c length or to repair a broken fi ber link.

But while fusion splicing is primarily used on singlemode fi ber in long-haul OSP appli-cations, it also occurs in premises LAN appli-cations for both singlemode and multimode fi ber types. And in data centers, the emphasis on density and performance combined with the need to ensure a return on investment has some installers opting to fusion splice rather than perform fi eld terminations.

New prices and trendsFusion splicing involves the use of localized heat to melt together or fuse the ends of two optical fi bers. Th e preparation process involves removing the protective coating from eachfi ber, precise cleaving, and inspection of the fi ber end-faces. (Inspection is critical since splice loss is directlyrelated to the angle and quality of the endface.) Once the fi bers are properly prepared, they are placed into thefusion splicer, aligned, and fused together.

Fusion splicing yields a very low loss of typi-cally less than 0.02 dB and, therefore, has lit-tle impact on overall link performance.

Th e two basic types of fusion splicing tech-nology in use today are core and V-groove alignment systems, with the core type align-ing a single fi ber and off ering better accuracyand lower loss.

“Th e core alignment splicer is the primary choice of any contractor doing fusion splicing, because you never know what type of specifi cations and loss budgets you’re go-

ing to be required to meet,” says Greg Pickeral, product man-

ager of fusion splicing for AFL Telecommunica-tions, a subsidiary of

Fujikura Ltd. of Japan (www.afl tele.com). “When you’re dealing with many fi bers, a

multi-fiber V-groovesplicer is a more ef-

ficient method, but the

Fusion splicers are small and portable enough for the data center and central offi ce. The Fujikura SpliceMate (FSM-11) is one of the world’s smallest and most portable fusion splicers.

design engineer must understand the tradeoff inaccuracy and loss estimation, and properly design around it.”

Today’s fusion splicers range in cost from $7,000 to $40,000. Th e highest-priced units are designed for specialty opticalfi bers, such as polarization-maintaining fi bers used in the production of high-end non-electrical sensors. Th e lower-end fusion splicers, in the $7,000 to $10,000 range, are primarilysingle-fi ber fi xed V-groove type devices. Th e popular core alignment splicers range between $17,000 and $19,000, well below the $30,000 price of 20 years ago.

“Th e prices have dropped dramatically due to more effi -cient manufacturing, and volume is up because fi ber is no longer a voodoo science and more people are working in thatarena,” says Pickeral. “Recently, we’ve seen more fi ber beingdeployed closer to the customer premise with higher splice-loss budgets, which results in a greater participation ofVerizon and AT&T installers who are purchasing lower-end splicers to accomplish their jobs.”

According to Pickeral, in fi ber-to-the-premises (FTTP)applications, fusion splicing is now being used to install con-nectors for customer drop cables using new splice-on connec-tor technology and lower-end V-groove splicers.

“Historically, the choices were to either fusion splice on a pigtail or install connectors in the traditional hand-polishing method where consistency, insertion loss, and other perfor-mance measurements are determined by the installer’s abil-ity,” says Pickeral. “Th e newest fusion-installable connectors use fusion splicing to connect the ferrule to the fi ber, and then the connector is assembled around the splice.”

Pickeral says the new splice-on connectors let service provid-ers build customer drop cables to length so they don’t have to deal with slack storage at the curb or customer location.

Behind closed doorsTh e fi rst and primary use of splicing in the telecommunications industry is to link fi bers together in underground or aerial out-side-plant fi ber installations. Over the past 15 years, severalinnovations have drastically reduced the amount of fusion splicing taking place in the premises environment, including advancements in fi eld installable no-epoxy/no-polish connec-tors and indoor/outdoor cables.

According to Warren Hicks, manager of marketing strategy and development for private networks at Corn-ing Cable Systems (www.corningcablesystems.com),

“It used to be very common to do fusion splicing at the building entrance to transition from outdoor-rated to indoor-rated cable,because the NEC specifies that outdoor-rated cable can on-ly come 50 feet in-to a building

due to its fl ame rating.” He adds, “Th e advent of plenum-rat-ed indoor/outdoor cable has driven that transition splicing to a minimum. But that’s not to say that fusion splicing in thepremise isn’t going on.”

Hicks believes that longer distances in the outside plant could mean that sticking with standard outdoor-rated cable andfusion splicing at the building entrance could be the more eco-nomical choice.

“It’s important to do the math,” he says. “If it’s a short runbetween building A and B, it makes sense to use newer indoor/outdoor cable and come right into the crossconnect; however, because indoor/outdoor cables are generally more expensive, if it’s a longer run with lower fi ber counts between buildings, it could ultimately be cheaper to buy outdoor-rated cable and fusion splice to transition to indoor-rated cable, even with the additional cost of splice materials and housing.”

Hicks continues, “It oft en comes down to who’s driv-

Mass fusion splicers, such as the Fujikura FSM-50R12, are based on V-groove technology and can splice 12 fi bers at a time.

Corning Cable Systems’ UniCam MTP connectors offer a no-epoxy/no-polish fi eld-installable MTP/MPO style that provide an alternative to fusion splicing or preterminated trunk cables in the data center.

ing the boat. If it’s the contractor, and he has access to afusion splicer, he may take the time to do the calculation anddetermine which option is less expensive, because that can mean a higher margin for him. If the end user is driving it, they may decide they don’t want the loss associated with the transition splice and choose the indoor/outdoor cable.”

While fi ber-to-the-desk applications remain rare, it isanother situation that may call for fusion splicing in the prem-ises environment.

“If you want to go the full 300 meters in a fi ber-to-the-desk application, you have to either fusion splice or do an intercon-nect; however, an interconnect can introduce 0.75dB of loss while the fusion splice is typically less than 0.02dB,” Hicksexplains. “Th erefore, the easiest way to minimize the amount of loss on a fi ber-to-the-desk circuit is to bring the individual fi bers from each workstation back to the closet and then splice to a higher-fi ber-count cable.” Th is approach also enables cen-tralizing electronics for more effi cient port utilization.

Fusion splicing in the premises is more common with sin-glemode fi ber applications because many customers are stilluncomfortable with fi eld-installing singlemode connectors.

“We have some customers futureproofi ng with singlemode

fi ber, and instead of the more diffi cult task of fi eld-polish-ing singlemode connectors, they have chosen to fusion-splice preterminated pigtails,” says Rudy Montgelas, senior prod-uct manger of fi ber optics for Ortronics/Legrand (www.ortronics.com). “Th ere’s more variation and higher loss when fi eld terminating fi ber connectors, while the factory-termi-nated connectors on a pigtail ensure a premium polish and better performance. Because fusion splicing can provide very low loss, fusion splicing to factory-terminated pigtails canresult in better performance.”

An option for data centersA signifi cant increase in the number of applications support-ed by data centers has resulted in more cables and connec-tions than ever, making available space a chief concern. As a

Some installers choose fusion-splice fi ber pigtails, like these factory-terminated LC fi ber pigtails from Ortronics.

result, many data center managers are turning to higher-den-sity solutions like MTP/MPO (mechanical transfer pull-off /multi-fi ber push-on) connectors and multi-fi ber cables that take up less pathway space than running individual duplexcables. Since few manufacturers off er fi eld-installable MTP/MPO connectors, many managers are selecting either mul-tifi ber trunk cables with MTP/MPOs factory-terminated on each end, or fusion splicing to preterminated MTP/MPO or multifi ber LC pigtails.

“We are seeing higher usage of handheld V-groove-basedfusion splicers for termination applications in the premise and data center environment,” says Josh Seawell, product

manager for fusion splicers with Sumitomo Electric Lightwave (www.sumitomoelectric.com). “Fusion splicing provides permanent low-loss connections that are performed quickly and easily, which are defi nite advantages over competing technologies. In addition, current handheld fusion splicers are designed to pro-vide enhanced features and high-quality performance, and be very aff ordable at the same time.”

According to Ortronics’ Montgelas, splicing in the data center involves the use of a splice tray for stor-ing and organizing the splices. “Splice trays can be

located in the back of a patch cabinet, or for very high-density splicing, the splice trays could be located in a separate splic-ing cabinet,” says Montgelas. “Th e tradeoff between the labor, equipment, and materials involved in fusion splicing versus the cost of the factory-terminated trunk cable needs to be consid-ered on a case-by-case basis.”

Montgelas adds: “When you select trunk cables with connec-tors on each end, data center managers oft en specify lengths a little bit longer because they can’t always predict exactdistances between equipment and they don’t want to be short; however, they then have to deal with excess slack. When there are thousands of connections, that slack can create a lot

MPO connector that is built around our Unicam technology,” says Hicks. “Th e UniCam MTP can be terminated in the fi eld in about four minutes.”

While the UniCam MTP con-nectors pass all industry stan-dards and tests for optical performance, each one involves a mechanical splice, which con-tributes slightly higher loss than a fusion splice.

“If I already own a fusion splicerand space isn’t an issue, I may choose to fusion-splice factory-

terminated pigtails to achieve lower loss,” says Hicks. “But our stance is that the fi eld-installable connectors are the most eco-nomical method because you’re eliminating the capital expense of a fusion splicer, eliminating the expense of additional splic-ing materials and consumables, and maximizing density in the rack by eliminating the need to accommodate splice trays.”

Making the choiceToday’s fusion splicers “off er many advantages in the premisesenvironment, from being lightweight and compact to operat-ing on a battery,” says Sumitomo’s Seawell. “Th ese new units minimize setup time and are ideal for use in locations where space is tight. In addition, the total splice and heater cycle time is less than one minute, thereby enabling technicians to move through many termination locations quickly.”

Adds Hicks: “We foresee fusion splicing decreasing, because ultimately, customers that can’t deal with slack are going todemand fi eld-installable connectors. Many more will rely on the preterminated trunk cables and sacrifi ce the inconvenience of dealing with slack, because it off ers faster deployment.”

Montgelas says that preterminated solutions off er the most benefi ts: “It’s easy to install preterminated cables, and because they’re available in custom lengths, it’s easy to get the exact lengths required to limit the excess slack.”

When deciding between fusion splicing and fi eld-installable connectors, Montgelas says there are other factors to consider:

“Fusion splicing is taking on more of an interest in the datacenter for singlemode applications, but compared to howmuch it will take off versus fi eld-installable connectorsremains to be seen.”

He concludes, “As you get into significantly higherfi ber counts, fusion splicing could save time over installing connectors; however, contractors and installers that don’t have a fusion splicer or splicing experience may want to consid-er whether to invest in a fusion splicer and the cost and timerequired to train their staff .”

of congestion and limit prop-er air fl ow and cooling. One alternative is to purchase a multi-fi ber pigtail and then splice to a multi-fi ber cable, which some installers are choosing to do.”

Sumitomo’s Seawell notes, “Projects utilizing MTP/MPO-style connectors cou-pled with the use of ribbon fi ber or the ability to ribbon-ize single fi bers allow users to experience significant time savings by fusion splic-ing multiple fi bers at once. Imagine splicing four, eight, or 12 fi bers in the same time frame as splicing only one fi ber. Th is is possible using mass- or ribbon-fusion splicers. Mass-fusion-splicer technology has been around for decades and now is available in handheld models, such as Sumitomo’s Type-25eM TomCat 4-ct ribbon splicer.” Seawell adds that another of his company’s products, the Type-66 Tuff Cat 12-ct ribbon splicer, can accommodate larger fi ber counts.

Corning Cable Systems is one of the few manufacturersoff ering a fi eld-installable MTP connector, which is anotheroption for those data center customers that don’t want to pur-chase pre-terminated trunk cables and deal with slack. “MTP/MPO connectors are diffi cult to terminate using the epoxy-polish method; however, we off er a no-epoxy, no-polish MTP/

data center

The vexing problem of heat generation in the data center and, more specifi cally, within racks and enclosures is top-of-mind and top-of-agenda for professionals who manage such high-den-sity computing environments.

“Th e IT [information technology] world knows the two critical concerns in the data center are power availability and cooling capacity,” says Herb Villa, technical managerwith Rittal Corp. (www.rittal-corp.com). Th e two areinterrelated in that the equipment required to cool these spaces consume signifi cant amounts of power.

Dense servers known as blades are the primary sourcesof this concentrated heat. Quite oft en, blade servers are stored in enclosures or cabinets. Over the past severalyears, and with increasing frequency more recently,enclosure manufacturers are designing their wares to deal with concentrated heat loads in some form or fashion.

Villa notes that Rittal off ers a full breadth of products with thermal-management capabilities: “You have to be able to support customers who will put a few servers in a cabinet in a data room, as well as high-end users.” Th e products and technologies designed to support low and medium heat-load densities are pretty well established, he says, and include server cabinets with characteristics that include perforated doors and mounting rails. Typ-ically, enclosures of this sort can accommodate 8 to 10 kilowatts of heat per cabinet.

Liquid-cooled methodTh e technology that has gotten Rittal the most press the past few years, however, has been its closed-loop close-coupled solution. Th is proprietary liquid-cooled solution uses water rather than air as the cooling agent. “Every-one understands the physics of water versus air,” Villa states. “We know that refrigerants, such as water and gas,

have much greater heat-transfer and -carrying capaci-ties than traditional air.”

Villa further explains the liquid cooling package’s characterization as a closed-loop, close-coupled system:

“‘Close-coupled’ means the heat transfer and removal process is adjacent to the heat-producing component. ‘Closed-loop’ means air in the enclosure is circulated through the enclosure,” via fans.

Four or fi ve years ago, the prospect of introducing chilled liquid so close to a data center’s central nervous system made many feel, well, nervous. “Customers would say, ‘I’m not bringing water into my data center,’” Villa recalls. “Yet they already had water in their data center in many other aspects,” including sprinkler systems.

Happily, he reports, “We have overcome the water big-otry. People realize they need to consider these solutions for high-density cooling.” Whereas a half-decade ago, Villa’s potential customers would ask him why they’d ever put water into their enclosures, today, they’re ask-ing other questions. Namely, he says, “How do we get it installed, and what is the total cost of ownership/return on investment? (TCO/ROI)”

Villa reports that Rittal has completed one study and is working on another that can, in fact, quantify TCO and ROI. Savings can be realized, Villa explains, by reducing the number of enclosures needed to house servers, thereby saving fl oorspace. Additionally, the water-cooled system lets users turn off and/or not have to purchase computer room air conditioning units (CRACUs), which can, above and beyond saving the costs of these units, entitle some data centers to rebates from their electric utilities.

A versatile approachPanduit (www.panduit.com) recently introduced the Net-Access Server Cabinet, adding it to a product line that already included the Net-Access Switch Cabinet. ➤

Enclosures play a role in thermal management

Dealing with heat close to its source takes several forms.

While the two systems’ dimensions are the same, the compo-nents within them make them appropriate for housing either switches or servers.

Panduit’s business development manager, Charles Newcomb, explains: “Th ermal management is very diff erent for eachapplication. In general, switches breathe side-to-side while servers breathe front-to-back. Cable management is key in these environments, and it is important to have a cabinet that allows you to properly route cables—to route them away from switch exhaust and intake.”

Newcomb says that switches “typically do not comply with hot-aisle/cold-aisle designs, so the Net-Access Switch Cabinet was specifi cally designed to provide large pathways for cable routing and airfl ow. To optimize switch performance, exhaust ducting direct hot air from the switch out of the cabinet to the hot aisle.” He adds, “A server application is very diff erent. It is important

to block airfl ow between the cold aisle and hot aisle. Blanking panels ensure air cannot pass from cold aisle to hot aisle.”

Cable management is important here too, Newcomb says, but it presents a diff erent set of challenges. “A server cabinet contains lots of cables, but of diff erent types—power, as well as copper and fi ber communications cables,” he notes. “It is criti-cal to provide cable pathways to route cables away from server fans and remove airfl ow blockages behind servers. Th ose block-ages trap air inside, and force the server to operate at a higher temperature. A way to eliminate that is to allow the fl exibility to mount patch panels vertically. Th e width of the Net-Access Server Cabinet allows patch panels to be mounted outside the traditional 19-inch area.”

Marc Naese, solutions development manager with Panduit, adds, “Th e lifecycle of equipment in a data center can be two to three years; the lifecycle of a cabinet is much longer. Users expect their cabinets to be able to grow with the infrastructure, and serve them every time they change out equipment.”

Consequently, notes Naese, “most data center managers are moving away from 24-inch cabinets and going to a wider cab-inet, where they can effi ciently manage more equipment.”

Sealing off accessTh e merits of isolation between hot air and cold air are alsoevident in the TeraFrame series of enclosures fromChatsworth Products Inc. (CPI; www.chatsworth.com). Ian Seaton, the company’s technology marketing manager, refl ects,

“Everything that’s done in the data center, when you followindustry understanding of best practices, is really designed to sep-arate the supply air from the return air as much as possible. Th at’s why you want to seal off access cutouts, fl oor tiles, blanking tiles, and locate your cooling units in hot aisles so you prevent yourreturn air path from migrating into the cold-aisle space.”

Seaton continues, “All those design considerations and best practices that we defi ne as ‘best practices’ are geared to ac-complish as much separation as possible to keep supply air, asdelivered to equipment, from exceeding the clinical defi nition of what a hotspot would be.”

Chatsworth’s solutions continue on those best practices, Seaton says, but take them to an extreme. Th e company’s pas-sive cooling system represents one of three approaches to hot air/cold air isolation: “You can build a room around a cold aisle and keep it separate from the rest of the data center so your re-

turn air is in free space and returns to CRA-CU, without mixing with the cold aisle. Or, you can build a room around a hot aisle, and duct the air out of the room directly back to the CRACU, thereby keeping separation. Or, you can use a solution like ours, taking ad-vantage of your suspended ceiling plenum space and accomplish the same thing.”

Th e CPI system employs several accessories to accomplish hot-air/cold-air isolation, including raised-fl oor grommets, snap-in fi ller panels, mounting rails to seal the front of the cabinet from the back, and a vertical exhaust-duct system.

Th ese three manufacturers off er a sampling of the manyenclosure products available with some form of thermal man-agement built into them. Importantly, each vendor says their individual systems are not standalone solutions to the heating/cooling issues aff ecting data centers.

Next month, we will have further commentary from these and other industry experts on the topic of taking a holisticapproach to thermal management.

security

Over the course of just a couple of months, several announcements from the surveillance industry un-derscore the notion that the technology is increasingly moving in the direction of Internet Protocol-based delivery. Th e oft en-used-but-rarely-defi ned term “con-vergence” is typically invoked to describe a setup in which several systems run over a single, structured in-frastructure, and that term applies to several of the re-cent happenings in the security/surveillance industry.

On August 1, Schneider Electric (www.schneider-electric.com) announced it was acquiring security-sys-tems provider Pelco (www.pelco.com) for $1.54 billion in a deal expected to close this month.

According to the companies, Pelcowill report into Schneider Elec-tric’s Building Automation busi-ness unit, encompassing power and heating, ventilation, and air-condition (HVAC) control plus electronic security and fi re safety applications, and will assume leadership ofSchneider’s present Fire & Security product division.

“Th is acquisition signifi cantly reinforces our build-ing automation business unit,” comments Jean-Pascal Tricoire, CEO of Schneider Electric. “Pelco systems willintegrate gradually into our power and control solutions for buildings and infrastructure. Security off ers a highly attractive growth profi le and video is becoming the key application in the building management market.”

Arne Frank, executive vice president of Schneider’s Elec-

tric Building Automation business unit, adds: “Th e com-bination of our companies will create a unique portfolio of products, services and solutions in the building man-agement industry. Pelco’s unique position in IP-based vid-eo security represents a tremendous additional organic growth opportunity. With this acquisition, a very impor-tant additional step is made to further reinforce our lead-ership in open and integrated solutions for building IT.”

Th e fi nancial aspects of the acquisition break down as follows: Th e price to be paid for Pelco is $1,220 mil-lion, expressed as an enterprise value on a cash-free/

debt-free basis. In addition, Schneider Electric will pay to the sellers the net pres-

ent value of a tax benefi tresulting from the step-up of Pelco’s assets, representing $320 million. As a consequence, the

total price paid in cash at closing will be

$1,540 million. Pelco had a net debt of roughly $139 million as of June 30.

As the acquisition awaits T-crossing and I-dotting, Pelco continues to bring to market new IP-based video surveillance technol-ogies, some of which are designed to pro-vide a bridge between existing analog and new digital systems. Last month, the com-pany expanded its Endura IP video secu-

rity system with the addition of a new soft ware version, mapping tools, intelligence encoders, a gateway, and wireless encod-ers and transmitters.“Whether customers are

looking for a sensible migration path from analog to digital, a digital extension to an existing analog system, or a full digital system, the solution built on the Endura platform can evolve to meet customers’ demands,” says Rob Morello, Pelco’s senior product marketing manager for digital systems.

Other forms of partnershipMeanwhile, a major name in the IP-surveillance market-place has partnered with the market-share leader in struc-tured cabling systems. In mid-August, CommScope (www.commscope.com), provider of the Systimax and Uniprise brands, announced an alliance with Axis Communications (www.axis.com).

“In order to be more diligent and effi cient with securityprograms, many companies are merging physical security departments with IT departments,” comments Mark Peter-son, senior vice president of enterprise global marketing at CommScope. “In addition, many organizations are planning to add more intelligence to buildings, where data, building automation and safety and surveillance systems all con-verge on a single infrastructure platform. With this alliance, CommScope and Axis help bring the intelligent building tocustomers.”

According to Peterson, as part of CommScope’s Alliance program, the relationship with Axis Communications isexpected to open opportunities for CommScope to promote the idea of an intelligent building infrastructure to customers around the world by linking them to an expert in converged surveillance operations.

“In order to allow our customers to deploy a high-quality,top-performing, and seamless network for all IP devices, Com-mScope is combining our strengths in the physical infrastruc-ture space with the strength of companies that have their own unique expertise,” he continues. “In the security space, Axis has the clear leadership and expertise in IP-based video sur-veillance. We believe that the alliance represents a great way to help our customers receive exceptional intelligent build-ing solutions.”

Th e two companies plan to engage in cross-training pro-grams with their sales force. “We believe the training willassist with the delivery of prompt responses to customers’ needs,” says Peterson. “In addition, this alliance may culti-vate the need for more education within the consulting com-munity about convergence, recognizing the potential benefi ts from the collaborative designs of surveillance systems and IT network infrastructures.” ➤

“CommScope is helping us communicate more eff ectively to our customers the importance and benefi ts of an intelli-gent building network system where all applications, from servers to video surveillance system, are converged onto one infrastructure platform,” remarks Fredrik Nilsson, general manager of Axis Communications. “We are thrilled to have an opportunity to build upon CommScope’s expertise whiledelivering the latest converged video security solutions to our customers.”

Users taking noticeEnd-user organizations from many vertical markets are tak-ing particular notice of the theme of IP convergence. Th e pro-fessional organization ACUTA (www.acuta.org) is an example of such attention. Th e abbreviation originally stood for theAssociation of College and University TelecommunicationsAdministrators, but in time, the group’s scope went far beyond telecommunications technologies. While it has kept the name by which it has become known, today, ACUTA bills itself as the

Association for Communications Technol-ogy Professionals in Higher Education.

ACUTA recently announced the agenda for its fall seminars, being held this month in Minneapolis, MN. Educational sessions concentrating on converged mobile com-munications will address topics such as campus Wi-Fi, wireless local networking, mobile phone fi nancial issues, and mobile integration. On the business continuity and disaster recovery side, presenters will covertopics that include campus emergencyresponse, emergency notifi cation options, and campus security issues. A “simulated IT department disaster” will also be staged.

“Th is year’s Fall Seminars will deal with some of the most pressing issues facing ACUTA member colleges and universi-ties,” comments Jeri Semer, the organiza-tion’s executive director. “How to cope with the surge in wireless communications and deal with emergencies on their campuses are major concerns today. In our seminars, the educational sessions combine withextensive networking opportunities, so communications technology professionalscan learn from each other, developinginformation sources and contacts that ben-efi t them and their institutions.”

More and more, professionals concerned with enterprise communications systems and their infrastructures are required to become knowledgeable of several dif-ferent systems. While those systems still include voice and data transmission, some-times voice and data are one and the same, as in Voice over Internet Protocol. Ad-ditionally, security applications of manystripes, including surveillance, emergencyresponse, and access control, are nowwithin the realm of communications sys-tems managers’ responsibility.

Incorporating a patented dry loose-tube technology in a smaller outside

diameter, Berk-Tek’s new Micro Data

Center Plenum (MDP) fi ber-optic cable technology is designed to relieve conges-tion in the data center and storage area

Berk-Tek unveils smaller diameter fi ber cable for data centers

The MDP cable design for data center and SAN installations incorporates Berk-Tek’s patented dry loose-tube technology in a smaller outside diameter.

A pioneering 40-Gbit optical active cable

Blazar, a 40-Gbit optical active cable (OAC), and billed as the world’s fi rst CMOS Photonics product, will combine the benefi ts of optical modules and copper

cables to deliver a high-bandwidth interconnect solution for Infi niBand and 40-Gbit proprietary rack-to-rack interconnect applications.

With support for Quad Data Rate (QDR), the singlemode cable’s 40-Gbit band-width and extended reach up to 300 meters is designed to overcome speed and range barriers that have limited In-fi niBand applications to small computer clusters. Developer Luxtera (www.luxtera.com) says Blazar will enable Infi niBand to become “a ubiquitous data centerinterconnection” for a wide range of appli-cations that require higher capacity and performance.

“This is a groundbreaking technology,” says Jag Bolaria, senior analyst at TheLinley Group (www.linleygroup.com). “Migration to 40G connectivity allows for denser clusters, and the 300 meter range extends the reach of these clusters. This should have a positive impact for high-performance computing and data centers.”

Luxtera says Blazar will enable data center managers to fully populate racks with servers and switches, eliminating the need to expand physical facilities to increase computing capacity. In addition, the cable’s power consumption is rated at 2.2 watts per cable end, resulting in 0.05 watts per gigabit of data, reducing the overallpower consumption required by data centers to power network equipment, and sig-nifi cantly reducing cooling costs.

By permanently attaching fi ber cable to optical transceivers, and powering four transmitters with a single hermetically sealed laser, Blazar is designed to reduceinstallation and maintenance costs while providing more reliability compared to typi-cal VCSEL-based technologies.

Blazar connects to a system via a QSFP MSA-compliant connector cage. The elec-trical cage is SFP+ compliant, which enables it to support data rates of 1 to 10.5 giga-bits per transport lane, for a total throughput of up to 42 Gbits/sec.

Luxtera will begin sampling Blazar later this year, with production quantities avail-able in 2008.

network (SAN).Th e MDP cable’s patent-pending con-

struction provides 50% smaller cross-sec-tional area than comparable fi ber-count indoor cables, which Berk-Tek claims will help prevent cabinet and pathway congestion by enhancing airfl ow andallowing more effi cient cooling.

With plenum ratings up to 72 fi bers, the MDP cables are available with alu-minum or steel interlocking armor, as well as pre-terminated cable assemblies with multi-fi ber MTP/MPO connectors or single-fi ber type connectors (e.g., SC, ST, and LC).

“Th e MDP boasts a size and weight that is half that of competing cable designs, and has made possible specifi c enhance-ments to system performance, reliability, modularity, and fl exibility in the NetClear [partnership with Ortronics] solutions for high-density data centers and storagearea networks,” says Beni Blell, RCDD,fi ber-optic product business manager at Berk-Tek.

“When combined with the Ortronics (www.ortronics.com) 12- or 24-fi ber MPO low-loss cassettes and cable management systems,” Blell claims, “a far superioroff ering to the data center/SAN systemdesigner has now been made available.”

Berk-Tek says that, compared to tra-ditional ribbon interconnect, premises distribution, and indoor/outdoor loose tube cables, the MDP off ers “improved density, ease of installation, termination, and sub-unit handling.”

Cables are off ered in multimode and singlemode fi ber construction.

Blazar, said to be the industry’s fi rst 40-Gbit optical active cable, combines optical modules and copper cabling to provide high-bandwidth interconnection to the data center.

Hybrid connector solutiondeveloped for harsh environments

Applied Optical Systems (AOS;appliedopticalsystems.com) has

developed a long-distance hybrid ca-bling system built to carry electrical and multi-channel fi ber optics for LAN and wireless LAN (WLAN)in harsh environments.

Th e F-Link family of products is equipped with up to 34 fi ber-optic channels and a fi ber-optic backshell, plus plug-and-play connectors and terminals. While comparable opto-electrical systems have connectors that can withstand 20 to 30 pounds of strain, the F-Link connectors are designed with a strain resistance of 250 to 400 pounds (depending on quality of fi ber or compos-ite cable), making it suitable where high winds or rough handling may occur.

In addition to many industrial ap-plications, F-Link is also being used in portable classrooms for school districts, where frequent handling and vandalism are issues. Th e Albuquerque, NM Public School District, for example, owns more than 1,300 portable buildings, and each year, 150 or more of them are relocated.Substantial costs result from hiring a con-tractor to disconnect and re-connect the data communication lines that integrate the classroom with the school.

“It costs tens of thousands of dollars every time we have to cable a group of portables,” explains Doug Ahlgrim, RCDD/NTS, of Albuquerque-based Sound & Signal Systems. “Th at was much too wasteful, so we developed a ‘quick disconnect’ plug-and-play design that would facilitate hooking up or un-hooking a hybrid plug-and-play design that would facilitate connection or dis-connecting all low-voltage systems.”

To ensure lasting performance and durability, Ahlgrim’s team had toaddress New Mexico’s seasonal temper-ature extremes, rough treatment of the

connections, and vandalism. Research-ing a supplier of plug-and-play opto-elec-trical technology led Ahlgrim to AOS, whose products include ‘tactical’ fi ber-optic connectors conforming to mili-tary specifi cations.

“AOS tailored their F-Link platform to keep the cost down while also provid-ing a system that is robust and rugged enough for the environments we’re put-ting it in,” Ahlgrim says. “Continuous vandalism of the previous ‘quick discon-nect’ product led the school district to re-solve the issue with the fi rst installation of the F-Link interconnect system. When used with Optical Cable Corp.’s (www.

occ.com) MX-Series Messenger Cable, the pull strength on the F-Link solution

exceeds 250 pounds, and functions well in an outdoor environment.

Sound & Signal Systems replaced the previous broken connections with F-Link products on approxi-mately 40 portable buildings and, according to Ahlgrim, there has not been a single breakage problem since. He adds that the system has reduced overall costs from tens of thousands

of dollars to just hundreds of dollars per relocation.“We now have about 400 to 500

F-Link systems deployed within the dis-trict, and it’s growing every day,” says Ahlgrim. “Th ough the district is not real-ly seeing the huge savings yet, they’ll start seeing it as they move from area to area and experience the savings based on the ease and simplicity of un-plug and re-plug, saving on labor, repair, and replacement costs. Plus, connector inventory is greatlysimplifi ed, and maintenance personnel can be trained on a single, easy system.”

As a result of the success of the F-Link connector in the portable classrooms, the Albuquerque school district has de-cided to use it for its intercom, fi re alarm,security, and phone systems throughout all of its facilities.

(Freelance technical writer Ed Sullivan of Hermosa Beach, CA contributed to this article.—Ed.)

Applied Optical Systems’ F-Link long-distance hybrid connector system carries both electri-cal and multi-channel fi ber optics for LAN and WLAN applications.

RICHARDSON, TX—Network infrastructure developer CommScope (www.commscope.com) has formed an alliance with network video solutions provider Axis (www.axis.com) to deliver intelligent building solutions to its customers. “To be more diligent and effi cient with security programs, many companies are merging physical security departments with IT departments,” says Mark Peterson, senior vice president, global marketing/enterprise at CommScope. “In addition, many organizations are planning to add more intelligence to buildings, where data, building automation and safety and surveillance systems all converge on a single infrastructure platform. With this alliance, CommScope and Axis help bring the intelligent building to their customers.”

NEW LONDON, CT—Following tests conducted at the Nexans Data Communications Competence Center, Ortronics/Legrand (www.ortronics.com) and Berk-Tek (www.berktek.com) say their warranted NetClear GTX 10G UTP cabling system can be installed alongside existing NetClear structured cabling systems within the same pathway without performance degradation of either system. The tests placed Berk-Tek’s (a Nexans company) LANmark-10G Augmented Category 6 in the same raceway as LANmark-1000 and LANmark-2000 Category 6 cables.

Both were unaffected, with the LANmark-10G cable continuing to meet all requirements of the draft TIA 568-B.2-10 Augmented Category 6 specifi cations. “The performance of the LANmark-10G cable combined with the co-engineered Clarity 10G termination products from Ortronics allows the NetClear GTX channels to be intermixed with channels of lower category performance, without interference,” says Jim Frey, Berk-Tek copper products manager.

DUBLIN, IRELAND—A newly released study from Research and Markets, “2007 Global FTTH—Fibre Networks Becoming a Reality” (www.researchandmarkets.com/reports/544344), fi nds that fi ber-to-the-home deployment worldwide “will be much faster in areas where there are clear business models for it,” and that “education is just one of the important social aspects of fi bering up countries—interactive video is going to add that special element to education, which will make fi bre-optic networks even more important for community social structures.” The report provides insight and analysis into the trends and developments taking place in the FTTH sector, taking a global overview, as well as providing information targeting North America, Latin America, Europe, the Middle East, and Asia Pacifi c markets.

Advanced Fiber-optic Technologies

While copper-based cabling systems reach new engineering heights to accommodate today’s fastest available data rates, fi ber-optic systems can boast of having supported these applications for years. The relative stability of fi ber gives many users the impression that it is relatively dormant as a medium, with little technological development taking place. And still, the perception exists that an optical infrastructure brings with it a signifi cant cost hike over a mixed fi ber-and-copper plant.

This web-delivered seminar produced by Cabling Installation & Maintenance seeks to clarify some misconceptions and detail important information about the installation, use, and maintenance of fi ber-optic cabling systems. From cost comparisons, to what’s in the short- and long-term future, to getting the most of the installed fi ber plant, this seminar puts optical networking and cabling systems into perspective.

Without sophisticated digital signal processing techniques in the electronics, reliable transmission is no longer possible around that

frequency and for higher frequencies. This phenomenon sets a limit in bandwidth for twisted-pair cabling.

Near-End Crosstalk or NEXT measures the crosstalk signal that appears at the same end of the cabling link from which the test or disturb-

ing signal is launched. Figure 1 illustrates Near-End Crosstalk in a two wire-pair system. If transmission simultaneously takes place over

multiple wire-pairs as is the case in 1000BASE-T and 10GBASE-T, Far-End Crosstalk (FEXT) must be considered and tested as well (see

Figure 2).

The crosstalk depicted in figures 1 and 2 takes place between wire-pairs in one cable (wire-pairs wrapped in the same sheath). Alien

Crosstalk is the exact same phenomenon, but the crosstalk coupling now occurs between wire-pairs in different, adjacent cabling links.

Alien Crosstalk is a challenge for unshielded twisted-pair cabling (UTP) as it is the most significant disturbance or noise source for the

10GbE application when using UTP cabling. Figure 3 shows the Alien Crosstalk in a wire pair induced by wire pairs in adjacent cables.

Alien Crosstalk will be measured as Alien NEXT between wire pairs, as well as Alien FEXT. Since the combined impact of many wire-pairs in

the bundle upon the wire-pair under test (usually referred to as the victim wire-pair) must be assessed, Power Sum Alien NEXT (PSANEXT)

and Power Sum Alien FEXT (PSAFEXT) should be computed and evaluated for wire-pairs in a cabling bundle.

Figure 1 – Near-End Crosstalk (NEXT) measures

2 that

returns to the receiver side and competes with “Signal B to A” arriving at the same receiver over pair 2.

Figure 2 – Far-End Crosstalk (FEXT) measures the crosstalk induced in wire-pair 4 that travels the length of the cable in the

direction of the transmitted signal and competes with the clarity of “Signal 4” arriving at Receiver 4.

Testing Challenges for 10 Gb/s Ethernet

over Twisted-Pair Cabling

New installation and testing guidelines help combat Alien Crosstalk (AXTalk)

The standards for 10 Gigabit/sec Ethernet over twist-

ed-pair copper cabling (10GBASE T) are still in the

development stage. Many issues and requirements

have been defined in recent months; we expect the

standards on 10 Gb/s Ethernet will be finalized and

published in mid-2006. This paper provides an over-

view of the requirements for the twisted-pair cabling

and methods to measure and certify the performance

of the installed cabling system.

3-phase UPSSmartOnline 3-phase UPS systems fea-ture what the company claims is the smallest footprint in their class. Powerand battery components have been com-

bined into a single, com-pact module designed to save fl oor space. Th e UPS features on-line, double-conversion operation, IGBT technology that provides <3% total har-monic distortion, and

3-phase 120/208-volt hardwire input/out-put. A static bypass and manual main-tenance bypass are designed to ensure continuous availability by safely passing through AC power if the UPS requires maintenance. Battery runtime is scalable from 5 to 31 minutes at full load with the20-kVA model. Th e systems are available in 20- and 30-kVA base models, and two extended runtime models.

Network simulatorTh is 250-kilometer network sim-ulation module is designed as a platform for improved testing and measurement of fi ber networks, test equipment, and optical subsystems requiring extended channel lengths. It requires less rack space than com-parable simulators and eliminates daisy-chaining of multiple mod-ules to achieve longer length sim-ulation channels. Modules can be built to emulate virtually any network or scenario, with suchoptions as specific events atdefi ned locations, multiple connec-tion types, and multiple channels with varied lengths.
