First off you need a
special “crimping tool”. Below is an example of such tool. This one
is made by a company called Ideal and can also crimp RJ-11 ends

Now that you know what
you need to make your own ethernet cable(patch
cable). Lets begin by
figuring out what pairs of cables need to go where.

The standard
“Patch Cable” consists of 4 twisted pairs. White/Blue, White/Orange,
White/Green, and White/Brown.


To make your end your
need to align the pairs like this:

Once you have your
pairs straightened out trim them so that you can fit the jacket of the cable
into the RJ-45. Also you want each pair to fit snug all the way to the end of
the RJ-45 for maximum performance.

For the most part you
will mostly use a “Straight Through” cable. The “Cross
Over” and “Roll Over” cables are for special purposes.

It will take some
practice to perfect this. So don’t get frustrated when your end doesn’t look
like it came from the factory on the first try.

Good Luck!!
