- 3. 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

- 7. 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
- 8. 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.

- 13. 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.
- 15. Internal Cable Structureand Color Coding • Orange / Orange-white • Green / Green-white • Blue / Blue-white • Brown / Brown-white Prepared by Werkalem.H.
- 16. About the RJ-45Ends • The RJ-45 end is a 8-position modular connector RJ-45 (Register Jack)Jack and Plug Pinout Prepared by Werkalem.H
- 17. 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

- 22. Making connections -Tools • Cat6e cable • RJ45 connectors • Cable stripper • Scissors • Crimping tool Prepared by Werkalem.H
- 23. Making connections -Steps 1. Strip cable end 2. Untwist wire ends 3. Arrange wires 4. Trim wires to size 5. Attach connector 6. Check 7. Crimp 8. Test Prepared by Werkalem.H
- 24. Step 1 –Strip cable end • Strip 1 – 1½” of insulating sheath • Avoid cutting into conductor insulation Prepared by Werkalem.H
- 25. Step 2 –Untwist wire ends • Sort wires by insulation colors Prepared by Werkalem.H
- 26. Step 3 –Arrange wires • TIA/EIA 568A: GW-G OW-Bl BlW-O BrW-Br • TIA/EIA 568B: OW-O GW-Bl BlW-G BrW-Br Prepared by Werkalem.H
- 27. Step 4 –Trim wires to size • Trim all wires evenly • Leave about ½” of wires exposed Prepared by Werkalem.H
- 28. Step 5 –Attach connector • Maintain wire order, left- to-right, with RJ45 tab facing downward Prepared by Werkalem.H
- 29. Step 6 -Check • Do all wires extend to end? • Is sheath well inside connector? Prepared by Werkalem.H
- 30. Step 7 -Crimp • Squeeze firmly to crimp connecter onto cable end (8P) Prepared by Werkalem.H
- 31. Step 8 –Test • Does the cable work? Prepared by Werkalem.H.
