NOTE:

Strictly follow the pinouts in the above tables when identifying or making the two types of Ethernet cables. Otherwise, the communication quality might be affected.

Making an Ethernet cable

1.Cut the cable to a required length with the crimping pliers.

2.Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45 connector.

3.Untwist the pairs so that they can lay flat, and arrange the colored wires based on the wiring specifications.

4.Cut the top of the wires even with one another. Insert the wires into the RJ-45 end and make sure the wires extend to the front of the RJ-45 end and make good contact with the metal contacts in the RJ-45 end and in the correct order.

5.Crimp the RJ-45 connector with the crimping pliers until you hear a click.

6.Use a cable tester to verify the correct connectivity of the cable.
