Make A Network Cable and RJ45 Wall Jack

create your own network cables

Many people prefer to make their own network cables. There are a couple of reasons for this: It’s often cheaper to make your own, and you can make the cables just the right size for your setup, eliminating the clutter of excess cabling. These videos demonstrate proper techniques for making and testing your Cat 5e network cables, as well as using a punchdown tool to make wall jacks for your RJ45 connectors.

Making A Cat 5e Patch Cable


Notice the technique used to first expose the inside cables and then use the string to safely expose more cable. This helps reduce the likelihood of using wires damaged by your initial cut. This is why it is important to give yourself several extra inches when cutting your cable length.

The tester used after the video is a bit of an overkill, but if you have one similar to that it tests for continuity and confirms both the cable length and the fact that it is a straight-through patch cable.

The video did not go into detail regarding the wire order. When holding the RJ45 connector away from you with the tab on the bottom, the order should be as follows:

  • Pin 1 – Orange / White
  • Pin 2 – Orange
  • Pin 3 – Green / White
  • Pin 4 – Blue
  • Pin 5 – Blue / White
  • Pin 6 – Green
  • Pin 7 – Brown / White
  • Pin 8 – Brown

Once you properly insert and crimp the wires on both side, make sure you use a tester to confirm there are no issues with it. This will save you a lot of time troubleshooting later on.

Make An Rj45 Wall Jack

Rather than having your cable just protruding from the wall, you should make a wall jack.

As demonstrated in this video, it is important to use the proper punch tool to punch down and cut the excess wiring. Once done, you will have a clean, professional wall jack to plug your network cables into.
