How To Terminate A Cat 5 Cable

How To Terminate A Cat 5 Cable


If you’re a bit overwhelmed by the idea of terminating a CAT 5 cable, don’t worry. It’s not as bad as it sounds. Here are some steps to complete your task:

Strip the wire

The first step in terminating a cable is to strip the wire. The length to which you should cut depends on the type of cable you’re using, but it’s always important to trim at least 1/2 inch from each end of your wires. When making a connection between two RJ45 connectors, you’ll want to make sure that both ends are stripped equally so that they match up perfectly when inserted into each other.

Once all four wires have been trimmed and stripped, crimp them onto their respective parts of the connector by placing one under each tab and pushing down firmly until it clicks into place (you may need needle nose pliers for this). This will secure your wire into place so as not to come loose during installation or use later on down the road! You’ll want all four wires secured like this because otherwise there could be movement from side-to-side which would cause problems when using any kind of networking technology such as WiFi or Ethernet over twisted pair cabling technologies like Cat5e/6/7 cables.”

Cut the wire evenly

  • Cut the wire at a 45 degree angle.
  • Cut the wire so that there is enough wire to strip.
  • Cut the wire so that there is enough wire to crimp

Arrange the wire in the order

To start, the wires should be arranged in the order they are numbered. The colors on Cat 5 cables are also color-coded, but this does not always mean that each color represents one wire. Since there can be more than one wire in a single color, it is best to use the numbering system instead.

Wire number 1 is white/blue. Wire number 2 is white/orange and so on until you reach wire number 24 which is blue/green (or blue). After these four colors come two pairs of metallic colored wires: 25 red/white and 26 green/white (which should not be confused with green/blue). The final pair of colored wires are 27 brown/white and 28 brown/green (or just brown).

Push the wires into the connector

Once the wires are cut, push them into the connector. Make sure that all of the wires are pushed in evenly and that they’re in their proper order (blue-white, white-green, and green).

Terminating Cat 5 cable is easy if you follow these steps.

  • Strip the wires. The first step in terminating a Cat 5 cable is to strip its wires. This means you will remove the insulation from each strand of wire so you can attach a connector to them. When stripping wire, do not cut through any of the strands; instead, make sure that each strip is as equal as possible so that all five are even when we begin to twist them together later on. Once you have stripped the cable and arranged it in an orderly fashion in front of you (see illustration), click here for more information detailing how to properly prepare them.*
  • Cut each wire at an angle around 1/4 inch from where it emerges from its respective connector’s housing.* Push each into its respective connector until they reach their proper slots.* Push each one down until they’re flush with their housing.* Wrap all five pairs tightly around one another using a clockwise motion.* Attach crimp-on connectors onto both ends of your newly-terminated Cat 5 cable* Test your internet speed by going online with Speedtest!


Congratulations! You’re now a master at terminating Cat 5 cables. To recap, here are the steps you should take:

  • First, strip off about an inch of the cable jacketing.
  • Next, arrange each set of wires in order and trim them to length
  • Then, untwist the pairs and straighten them as best you can
  • After that, insert all 8 wires into the connector
  • Finally, crimp down on all 8 wires by squeezing firmly with your crimper or pliers until it clicks three times.

With these steps in mind and some practice, you’ll be able to consistently create reliable Cat 5 terminations. Thanks for reading!
