How to Crimp an RJ45 connector With a Cat6 LAN Cable

Materials Needed:

  1. Cat6/Cat5 LAN cable
  2. RJ45 connector
  3. Crimping tool
  4. Cable cutter

Step 1: Measure and Cut the Cable

  • Determine the desired length of your Ethernet cable and cut the Cat6 cable to that length. Use a cable cutter or a sharp utility knife to make a clean cut.

Step 2: Strip the Cable Jacket

  • Use a cable stripper or utility knife to strip off about 1.5 inches (3-4 cm) of the outer jacket from the end of the cable. Be careful not to damage the twisted pairs inside the cable.

Step 3: Untwist and Arrange the Wires

  • After stripping the jacket, you will see four twisted pairs of wires. Untwist the wires carefully. Try to keep the twists as close to the cable jacket as possible to maintain optimal performance.
  • Arrange the wires in the following order, from left to right: white-orange, orange, white-green, blue, white-blue, green, white-brown, and brown.

Step 4: Trim and Align the Wires

  • Use a wire cutter or scissors to trim the ends of the wires so that they are all even and aligned. The trimmed wires should be long enough to reach the front of the RJ45 connector.

Step 5: Insert the Wires into the RJ45 Connector

  • Carefully insert the wires into the RJ45 connector in the same order you arranged them. Make sure they go all the way to the front of the connector and stay in the correct order.

Step 6: Check the Wiring Order

  • Double-check that the wires are in the correct order, following the T568B standard for Ethernet connections, which is the most common wiring scheme. The order, from left to right, should be: white-orange, orange, white-green, blue, white-blue, green, white-brown, and brown.

Step 7: Crimp the Connector

  • Insert the RJ45 connector and cable into the appropriate slot on the crimping tool. Make sure the connector’s gold contacts are facing down.
  • Squeeze the crimping tool firmly and evenly to crimp the connector onto the cable. This will secure the wires in place and create a solid connection.

Step 8: Repeat for the Other End

  • If you’re making a patch cable, repeat the above steps to crimp an RJ45 connector onto the other end of the Cat6 cable.

Step 9: Test the Cable (Optional)

  • If you have a cable tester, you can use it to check the continuity and correctness of the wiring in the cable. This step is optional but recommended to ensure a proper connection.

That’s it! You’ve successfully crimped an RJ45 connector onto a Cat6 LAN cable. Repeat the process as needed to create custom-length Ethernet cables for your networking needs.
