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

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 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?
