Feature OverviewHigh-speed transmission systems employ laser sources with narrow bandwidths, which are sensitive to back-reflections caused by components, splices, and connectors. If too much light is reflected back to the laser transmitter, the modulation characteristics and spectrum of the laser may change. This change will degrade the systems performance. For efficient operation of the laser transmitter, it is necessary to test for optical return loss caused by back-reflections.

Note: Mostmanufacturersoffiberoptictransmissionsystemsspecifythemaximumallowablereturnloss for error free operation.

TheTURBOTEST500Boffersthelatesttechnologyinasinglefiberbi-directionallossandreturnlosstesting that provides the exchange of loss data and references between units. The instrument performs threefiberopticmeasurements:OpticalPower(OPM),OpticalReturnLoss(ORL),andOpticalLoss(OLTS)measurements.InautomaticTURBOmode,theinstrumentperformsbothOpticalReturnLoss(ORL) and Optical Loss (OLTS) measurements.

If the configuration is TRIPLE wavelength, theTURBOTEST500Bcanstoreupto460records.StoredtestresultscanbetransferredtoaPCfora complete report generation. For a complete description of the PC executable software, refer to the User’sGuidesuppliedwiththesoftware.

An optional dedicated digital TALK option is available for full time/full duplex communication between test operators while testing other fibers in a bundle.

Test jumpers with a variety of lengths and connector styles are available from Noyes.

Optical ports and connector end faces must be kept free from dirt or other contaminates to ensure accurate measurements and operation.

ForcleaningconnectorendfacesontheTURBOTEST500BVoiceandTestPorts,testjumpers,andinfiberframesoradapters,NoyesrecommendsusingourexclusiveFCC2non-hazardouscleaningfluidand CCT molded cleaning tips.

The FCC2 fluid is a non-flammable, environmentally safe, residue free solvent engineered to clean fiber connector end-faces.

The CCT molded cleaning tips introduce a new fiber connector end face cleaning technology. Rather than

a fabric-covered or foam-covered stick, we are offering a molded cleaning tip that will trap contamination and wick cleaning solvents from bulkhead connectors. This new cleaning tip is a molded, sintered polymer that is both porous and pliable conforming to virtually any fiber end-face polish geometry while trapping and absorbing contaminants.

CCT cleaning tips and FCC2 cleaning fluid may be combined into FCP1 fiber optic cleaning kits. Noyes offers a complete selection of FCP1 cleaning kits for field cleaning. The FCP1 Series of kits delivers compact, safe, easy to use, reliable cleaning for all types of fiber optic connector end faces.

Battery Maintenance

Battery Replacement

To replace a battery:

1 Remove the protective rubber boot from a unit.

2 Remove the battery compartment cover located on the back of the unit.

3 Replace the battery observing proper polarity.

4 Replace the cover and rubber boot.

Battery Recharging

When a low battery label - [BAT] is displayed on the test screen, the battery requires charging. The instrument will operate for approximately 1 hour (minimum) after the [BAT] label is displayed.

A battery can be recharged to full capacity in about three hours. To fully recharge the battery:

1 Connect the AC power adapter/charger to the Power Port.

2 ThebatterywillchargewhethertheTURBOTEST500Bispowered[ON]or[OFF].

Battery Indicator Lights

ThetwocolorLEDonthesideoftheTURBOTEST500Bshowsthepowerconditionofthe internalbattery when the unit is plugged into the AC adapter/charger. The green light indicates that the battery is fully charged. The red light indicates that the battery is charging via the AC adapter/charger (refer to Figure 2-1, page 4).

Note: To reduce noise, the AC adapter/charger will shut down during TURBO or OLTS tests. The [AC/charger] indicator will turn red. Once the test is complete, the indicator will turn back green.

TURBOTEST 500B MessagesThe following display messages are listed alphabetically for easy reference.

Message Cause/Meaning Solution

HI The amount of light detected is above the range of the TURBOTEST500B.

Be sure laser output is properly set in Laser Adjustment screenunderOPMmenu.Perform the required testprocedures over.

LO The amount of light detected is below the range of the TURBOTEST500B.

Clean all fiber optic connectors again and check for excessive fiber bends. Perform the required test procedures over. Be sure laser output is properly set inLaserAdjustmentscreenunderOPMmenu.Performthe required test procedures over.

Clean all fiber optic connectors again.

If operating in TURBO mode, perform the referencesetup procedures again. Refer to Section 4

If operating in OLTS mode, perform the reference setup procedures again. Refer to Section 6

Solving Test, Print and Software ProblemsThis section describes how to solve problems you may encounter while using the TURBOTEST 500B instrument or PC software.

Problem Cause Solution

The unit beeps twice when attempting to reach a return loss reference value of greater than 40 dB with the reference cable wrapped around the mandrel.

The reference cable could be dirty or damaged.

Clean the reference cable connectors and optical ports on the TURBOTEST500B.Checktheadapterforcracksordamage.Performthe reference setup procedures again using the newly cleaned jumper cable for accurate results.

If you are still unable to reach a return loss measurement greater than 50 dB, then the reference cable might need to be replaced.

The unit beeps twice when attempting to set the 14.6 dB (ORL) reference with an unwrapped reference cable.

The reference cable could be dirty or damaged.

If operating in OLTS mode, perform the reference setup procedures again. Refer to Section 6

With properly cleaned or newlysuppliedAPC/UPCreference cables, the unit does not show close to 14.6 dB of return loss.

Unitneedstobereferenced to the test cable.

Perform the reference procedure again for terminating the fiber around the mandrel. Select a single wavelength mode and remove any mandrel wraps on the test cable.

PresstheMENUkeytoaccessthe“[MAINMENU]”screen.

Select REFERENCES > ORL - 14.6 dB, then press SET.

The unit will display the return loss value within 0.2 dB of 14.6 dB at the selected wavelengths. The unit is now referenced to the test cable at the selected wavelength.
