6 Simple Steps for Data / Network Cabling

Perhaps the most difficult to achieve is the crimper , which is the tool with which we will fix the RJ-45 plug to the cable. They can be found for sale online for about 15 euros, although if you are not going to make cables frequently and you want to save the money the best is to ask a friend if he has one. There are crimping machines that, in addition to allowing “crimping” RJ-45, can also be used for RJ-11 (telephone cable). If you are not going to use cable of the latter type, it is best to buy a simple one because they are cheaper.

1. Peel the cable carefully

The first step is to peel about 3 cm. The plastic cover of the network cable at one of its ends. When performing this operation, care must be taken not to damage the internal pairs of the cable. To do this, we can use the blade that normally comes with the crimpadoras, but personally I find it easier to do it with normal scissors and currents. Make a not very deep cut and then pull to remove the excess plastic.

2. Separate cables and stretch them

Once we have the pairs in the air, we can see that they come twisted two by two (that’s why twisted pair). We have to “untangle” them and stretch them as much as possible, avoiding curves or angles. The more straight they are, the better. In addition we can take advantage to separate them a little, which will be useful for the next step.
