How to Assemble Cat5 Patch Cables

  1. Strip the cable jacket back a couple inches from the end of the cable.  This makes the wires easy to sort.
  2. Sort the pairs in the order shown on the diagrams below.
  3. Cut off the excess about 1/2 inch from the end of the jacket.
  4. Insert the pairs into the connector.  The wires should each go all the way in.  The jacket should insert far enough in to be crimped.
  5. Crimp the pins with a crimp tool
  6. Repeat for other end.

Tips
  • Make sure the jacket goes into the connector far enough to be crimped or wires will not only look bad, but they will be prone to failure.

  • Wires un-twisted for more than 1/2 inch make a poor quality connection.  

  • Cat5 wiring should not be run parallel to electrical wires.  Cross electrical wires at 90.

  • Deep Surplus has greant prices and service when it comes to keystone jacks, plates or anything else you need for networking. Their 8-port surface mount boxes are a good way to tame all the cat5 in your wiring closet or furnace room.

How to wire cat5 for data & voice in the same cable
