Step-by-Step Cat5e Wiring Tutorial
Cat5e cable is used to network devices together. (ethernet cable 4 image by BlueMiniu from

Ethernet cables allow you to network devices together. Cat5e cable, formally called ANSI/TIA/EIA 568A-5, is an enhanced backward-compatible version of standard Cat5 cable rated for longer networking-distances. Wiring a Cat5e network cable is identical to wiring a normal Cat5 cable. The primary difference is the actual wire. You can wire a Cat5e cable yourself in about 15 minutes with a few special tools.

Skill level:

Things you need

  • Cat5e cable
  • Wire cutters
  • Measuring tape
  • Vinyl boots
  • Cable stripping tool
  • RJ-45 jacks
  • RJ-45 crimping tool

  1. 1

    Cut the Cat5e bulk cable to the necessary length. Although Cat5e cable is efficient up to about 1,100 feet, shorter cable ensures that no information is lost. Measure the distance from the devices you wish to connect with the Cat5e cable, using a tape measure if you're unsure.

  2. 2

    Slide a vinyl boot onto each side of the cable, with the open end facing the end of the cable. Vinyl boots make your Cat5e cable more resilient. They also give your cable a tidy, finished look.

  3. 3

    Untwist the pairs of coloured wires on one side of the Cat5e cable and fan them out.

  4. 4

    Order the wires from left to right as: orange/white, orange, green/white, blue, blue/white, green, brown/white, brown.

  5. 5

    Insert the coloured wires into the RJ-45 jack, with the tab on the RJ-45 jack facing away from you. Push the coloured wires into the jack securely. Verify that the order of the wires is correct.

  6. 6

    Place the RJ-45 jack in the end of the crimping tool. Keep the wires pressed snugly inside the jack. Press the crimping tool together to lock the RJ-45 jack on the end of the Cat5e cable.

  7. 7

    Add a RJ-45 jack to the other end of the cable, following the same process.

  8. 8

    Slide the vinyl boot against the jack at the end of the Cat5e cable.

Tips and warnings

  • The incorrectly placement of the coloured wires can cause the Cat5e cable to malfunction.
