Working with twistedpair • Twisted pair cable is most commonly used in network installations • The TIA/EIA organization defines two different patterns, or wiring schemes, called T568A and T568B • Each wiring scheme defines the pinout, or order of wire connections, on the end of the cable. Prepared by Werkalem.H
Two types ofcables • Using the T568A and T568B wiring schemes, two types of cables can be created: • Straight-through • Crossover The straight-through and crossover cables each have a specific use on the network. The type of cable needed to connect two devices depends on which wire pairs the devices use to transmit and receive data. Prepared by Werkalem.H

Construct and TerminateTwisted Pair Cables • Identify and describe the cross-over and straight through cable pinouts and color codes Prepared by Werkalem.H.
9.
Types of cables •Two devices directly connected and using different pins for transmit and receive are known as unlike devices. • They require a straight-through cable to exchange data • Devices that are directly connected and use the same pins for transmit and receive, are known as like devices. • They require the use of a crossover cable to exchange data. Prepared by Werkalem.H
Tools Required • CAT6e Cable - bulk Category 5, cable • RJ-45 Ends • Crimper for RJ-45 • Wire Cutters - to cut and strip the cable if necessary • Cable Tester Prepared by Werkalem.H
14.
What is anEthernet cable? • Inside the cable, there are 8 color coded wires. • Wires are twisted into 4 pairs of wires, each pair has a common color theme. One wire in the pair being a solid or primarily solid colored wire and the other being a primarily white wire with a colored stripe. Prepared by Werkalem.H.

Ethernet Cable Pinouts • A straight through cable used to connect to a hub or switch, and • A cross over cable used to operate in a peer-to-peer fashion without a hub/switch. Prepared by Werkalem.H
