How to Make Ethernet Cables

Ethernet is an indispensable component of Internet and home networks. Majority of the home networks use Ethernet cables to join either their routers to their computers, or their modem to their router. These are particularly essential for users who have not yet opted for wireless equipment.

Ethernet cables are never cheap. Prices escalate when one buys a 20+ feet prefabricated cable from electronic retail shops. However, it is cheaper to make your own Ethernet cable.

Supplies Needed for Making Ethernet Cables

  • Category 5 (CAT 5) Ethernet Cable – a cable without terminals on it
  • Wire Cutter/Stripper – an indispensable tool to fabricate Ethernet Cable
  • RJ45 Connectors – these are the terminals at the ends of the cable
  • RJ45 Crimping Tool – a tool used to crimp the tops of the cable
  • Network Cable Tester – a gadget that tests if cables are working properly

Ethernet Cable Making Instructions

  1. Measure the desired length of your cable, making sure it is not too long or too short, then affix 5 inches more. These extra inches will allow you some slack and give you space to work on.
  2. Strip approximately one inch off the cable.
  3. Untwist the cables until the rubber shield is reached, exposing a little of copper which will join the RJ45 connector.
  4. Position the wire correctly.
  5. For normal ends, the order of the connection starting from the top of the connector should be white-orange, orange, white-green, blue, white-blue, green, white-brown, and brown.
  6. For crossover cables: white-green, green, white-orange, blue, white-blue, orange, white-brown, and brown.
  7. Put the RJ45 connector on. The copper ends should touch the plates in the connector. If this is not the case, review and rearrange the wires so all of them connect.
  8. Crimp the wire using the RJ45 crimping tool. This completes the procedure for one end of the cable.
  9. Do the steps 2-8 for the next end.
  10. Connect the cable to the tester and see if all lights turn green. If all lights turn green, your cable is working properly. If they do not, cut the RJ-45 connector off and re-terminate the ends of the cable with a new one.
