How to wire Ethernet cables – Part 2

In part 1 of this series we saw details of Ethernet cables and RJ45 Jack & plugs. Now we will see more of Tools required for wiring of Ethernet cables.

Below shown is a very useful tool for crimping of Ethernet cables or Telephone cables to various kind of plugs like RJ45, RJ12 and RJ11.

Apart from crimping, the tool has also got other useful parts to do cutting & striping the cables.

Now let us do it.
1. Remove about 1 inch of outer insulation cover of the cable.
2. Straighten the different pairs of wire.
3. Arrange them in required sequence.
4. Hold them flat & cut as per required length of plug.
5. Check again & note the first pin color wire.
6. Holding properly, insert the wires into the plug. Do not worry, the guides
will make it easy to insert the wires properly.
7. Check once again the order of wires and see that outer cover is also
inserted into plug beyond pressing mark.
8. Place the plug into the proper slot. Squeeze the handles firmly to set the
contacts and secure the cable.

This is how it looks when the different colored wires are arranged and cut to proper length as per RJ45 plug.

After inserting wires to the plug, place the plug into the proper slot.

Squeezing two-three times will ensure proper crimping. And that is all ! Your Ethernet cable along with RJ45 plug is ready to go !

In next part we will see, what steps we have to take to ensure every thing is ok.
