Basic principles of copper cablesCables of plant

Twisted par: explanation, categories, sizes, frequency, UTP, STPCabling T568A and T568B scheme Applications of the twisted pair Conectore for utpConnectors for serial communicationsDescription of the coaxial cable

How works the coaxial cableCoaxial connectorsUsed for RF coaxial connectorsDedicated lines. Media and used signals.


4/57

Essential telecommunications copper cable unit is formed by twotwisted insulated conductors and with a uniform step to create abalanced circuit.

A wire is a strand of material, usually copper.


5/57

Copper is perhaps best known for his ability toconduct electricity .

Copper is not oxidized and is quite resistant to

the. Corrosion (impairment).


6/57

The ability to stretch in fine wires withoutbreaking.

Pure copper is very malleable (easy moulding).


7/57

Cold rolled copper has a resistance to tractionof between 3,500 and 4,900 kilograms per square centimeter.


8/57

Most cables contain certain elements in common:

A coating or an envelope of protection.Insulation to avoid short circuits between individual conductors.Spacers for preserving the electrical properties of the cable.


9/57

Types of cables

It is the meeting of two or more twisted pairs of drivers.


10/57

Its structure consists of a central conductor copper surrounded by insulation.


11/57

Regardless of its structure, the cables are three important features:

Mechanical characteristics. Electrical characteristics. Characteristics of transmission.


12/57

All wiring within a building iscalled collectively cableplant. Plant, i.e. a cablingsystem structured cabling is just a set of individualcables.


13/57

A form of connection in which two insulators are interlaced to have lessinterference, increase the power and reduce the crosstalk.


14/57

Cancellation only works if the signal travels through correct wires.


15/57

Telephone twisted yarn quality not suitablevoice for data transmissions.


16/57

The transmission characteristics of the mediumare specified up to a higher frequency of 4 MHz.

With this type of cable Ethernet networksimplemented 10BaseT.


17/57


18/57

The transmission characteristics of the mediumare specified up to a higher frequency of 20MHz.

It's an improvement category4, can transmit data up to100Mbps.


19/57


20/57

You can transmit data up to 10 Gbps and the transmissioncharacteristics of the medium are specified up to more than 600 MHzfrequency.


21/57


22/57

AWG (American Wire Gauge AWG), is an agency of standardisation on thewiring. AWG refers to the thickness of the wires. When the yarn thicknessincreases the AWG decreases.


23/57

They are twisted pairs used for different technologies of LANcables. Are inexpensive and easy to use.


24/57

It is isolated within a protective cover, with a specific number of braids per footcopper cables.


25/57

Structured cabling for computer networks named two types of rules:


28/57


29/57


30/57

The twisted pair cable is theoldest in the market and some

types of applications is the mostcommon. An example of twistedpair is system telephone, sincemost devices are connected tothe telephone via a twisted pair.


31/57

Using connectors called RJ, being the most commonly used the RJ-11 (4-pin),RJ-12 (6-pin), and RJ-45 (8-pin).


32/57


33/57


34/57

Serial ports were first interfaces allowing computers to exchange information.Serial refers to data sent by a single thread: the bits are sent one after the other.


35/57


36/57

There are two types: 25-pin to 9 pin, or 9-pin to 25-pin, which means female to male, or male to female.


37/57


38/57


39/57

Consists of hard copper as the core, surroundedof insulating material, theinsulator is surroundeditself with a cylindricalconductor, which is abraided fabric mesh andan external driver that iscovered with a plasticwrap.


40/57


41/57

Binary data are transmitted over cable copper by applying avoltage on one end andreception at the other. Thecoaxial cable is a transmission,a network with electrical effectscaused by the physical form of the cable line.


42/57


43/57

Coaxial cables are characterized because they have a central connector (usually called active), uses connectors called BNC (British Naval connector).


44/57


45/57

Used for application of radio frequency modulated as entertainmentand cable TV systems.


46/57

Work within specifications up to 11 GHz frequency .


47/57

Industry RF uses standard type names for coaxial cables.

Coaxial cable, is used to transmitradio frequency (RF).


48/57

Radio frequency, also called radio frequency or

RF spectrum.


49/57

Coaxial cable used in microwave.


50/57

This connector is the most used to makeconnections to many Wireless cards with PCIinterface.


51/57

Used by manufacturers toassemble it on their computersWireless, such as Wireless cardswith PCI interface.


52/57

It is a version with thread BNC connector.


53/57


54/57


55/57

Private line that is used to connectnetworks of local area of moderatesize to an Internet service provider and is characterized as a permanentconnection.
