Common network cable types
- Coaxial cable
- Unshielded twisted pair
- Fiber optic
UTP characteristics
- Unshielded
- Twisted (why?) pairs of insulated conductors
- Covered by insulating sheath
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)
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

Making connections - Tools
- Cat5e cable
- RJ45 connectors
- Cable stripper
- Scissors
- Crimping tool
Making connections - Steps
- Strip cable end
- Untwist wire ends
- Arrange wires
- Trim wires to size
- Attach connector
- Check
- Crimp
- Test
Step 1 – Strip cable end
- Strip 1 – 1½” of insulating sheath
- Avoid cutting into conductor insulation
Step 2 – Untwist wire ends
- Sort wires by insulation colors
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
Step 4 – Trim wires to size
- Trim all wires evenly
- Leave about ½” of wires exposed
Step 5 – Attach connector
- Maintain wire order, left-to-right, with RJ45 tab facing downward
Step 6 - Check
- Do all wires extend to end?
- Is sheath well inside connector?
Step 7 - Crimp
- Squeeze firmly to crimp connecter onto cable end (8P)
Step 8 – Test
- Does the cable work?
