The document discusses network cabling and making connections with Cat5 cable. It describes different types of network cables like coaxial, UTP, and fiber optic cables. UTP cable characteristics and categories are explained, with Cat5e being suitable for Gigabit Ethernet connections up to 1000Mbps for runs under 90 meters. The steps for making a patch cable connection are outlined, including stripping the cable, arranging the wires according to the TIA/EIA 568A or 568B standard, crimping an RJ45 connector onto the cable, and testing the connection.
Cabling
- 1. Network Cabling Making connections with Cat5 Way cool!
- 2. Overview What cable types are available? How do cables work? How are cables used in networking? How are connections made?
- 3. Learning Objectives List common cable types used in networking Describe how UTP cables are made Explain how UTP cables are used in Ethernet networks Demonstrate the ability to make a working patch cable Name the two wiring standards used for wired Ethernet networks and their uses
- 4. Common network cable types Coaxial cable Unshielded twisted pair Fiber optic
- 5. UTP characteristics Unshielded Twisted (why?) pairs of insulated conductors Covered by insulating sheath
- 6. UTP categories Category 1 Voice only (Telephone) Category 2 Data to 4 Mbps (Localtalk) Category 3 Data to 10Mbps (Ethernet) Category 4 Data to 20Mbps (Token ring) Category 5 Data to 100Mbps (Fast Ethernet) Category 5e Data to 1000Mbps (Gigabit Ethernet) Category 6 Data to 2500Mbps (Gigabit Ethernet)
- 7. Cat5e cable 1000Mbps data capacity For runs of up to 90 meters Solid core cable ideal for structural installations (PVC or Plenum) Stranded cable ideal for patch cables Terminated with RJ-45 connectors
- 9. Making connections - Tools Cat5e cable RJ45 connectors Cable stripper Scissors Crimping tool
- 10. 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
- 11. Step 1 – Strip cable end Strip 1 – 1½” of insulating sheath Avoid cutting into conductor insulation
- 12. Step 2 – Untwist wire ends Sort wires by insulation colors
- 13. 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
- 14. Step 4 – Trim wires to size Trim all wires evenly Leave about ½” of wires exposed
- 15. Step 5 – Attach connector Maintain wire order, left-to-right, with RJ45 tab facing downward
- 16. Step 6 - Check Do all wires extend to end? Is sheath well inside connector?
- 17. Step 7 - Crimp Squeeze firmly to crimp connecter onto cable end (8P)
- 18. Step 8 – Test Does the cable work?
- 19. Let’s go to work!
