First
of all, building quality network cables depends on ordering the correct
materials. The most important material will be the cable that we will be
using. Bulk Cat 6 cable is available in a variety of different types:
Step 1:
Before we start building our patch cable, you will need to cut a length of Cat6
cable. When cutting your cable be certain to make the correct measurements as
there is nothing worse than building a patch cord that will not reach.
Now we begin, by stripping the jacket back approximately 1 inch from the end. To do this, we like to use Ideal's 45-163 Coaxial Stripper.
Exercise caution when striping back the jacket, making certain that the blade depth of your strippers will not damage the conductors but will still cut through the jacketing. If you nick the conductors, it may work fine at first, however, after time the conductors will break or begin to short out.

Step
2:
Now that we have the jacket stripped back with the conductor pairs exposed, we
will need to separate and straighten them. You can start by pulling the first
pair and the last pair to their respective sides (Orange to the left and Brown
to the right). Untwist them, but not any further than you have stripped back
the jacket. Next we split the green pair. Pull the white/green conductor to the
left and the green to the right. This leaves you with the blue pair in the
middle. Untwist the blue leaving the white/blue conductor on the left and the
blue on the right.
Note: Normally, we wouldn't untwist Cat 6 pairs except when building patch cords. It would be next to impossible to insert the conductors into the proper locations in the connector without untwisting them. (Keep in mind you want to keep as much of the twist of each pair intact in order to meet performance standards).

Step
3:
Now that we have separated and straightened all of the pairs, we need to
arrange the conductors into the proper order according to which of the wiring
standards you would like to use. For this example we will be wiring via the
568-B standard (most common in patch cords). Please consult the pin-out
to find the proper color codes that reflect your desired wiring
standard. After you have all the wires arranged in the proper order,
place them tightly together as show in the picture to the left. Once you have
done this, verify that the wires are still in the proper order before
continuing to step 4.
Step
4:
Now we'll trim the conductors down to fit into the RJ45 connector. When
trimming, make sure to make a nice clean cut at a 90 degree angle about 1/2 of
an inch from the end of the jacket. If you fail to make a straight cut or cut
too short, some of the conductors may not reach the contacts in the connector.
If you leave the conductors too long, when crimping the connector, the
jacketing will not be gripped leaving all the strain on the conductors. This is
not a good situation! For proper trimming, hold the wires securely in
their proper order just at the end of the jacket.
Step
5:
Now that we have our Cat 6 patch cable prepped for termination, we are almost
finished. While still holding the cable firmly, we now need to place the
conductors into their proper location in the RJ45 Modular Connector. Hold
the RJ45 modular plug with the pins facing up (towards you) and carefully
insert the conductors holding firmly to be certain they retain their order. You
will need to use a moderate amount of force to properly seat the wires against
the contacts in the connector. When this is done, look at the tip of the
connector. As illustrated in the picture to the left you should be able to see
the end of each conductor indicating that they were fully inserted. Also take
note of the colors. All whites on the top and all the colored conductors on the
bottom.
Step 6:
Carefully insert the assembly which you have just completed into a modular
crimping tool. When crimping the connector you want to make sure you use the
full stroke of the crimp tool so that the contacts properly "bite"
into the conductors. After you have completed the crimp take time to look
at the connector and make sure all the pins were crimped and that they made
good contact with the conductors.
Step 7: If
you are building a straight through (standard) patch cord, terminate the other
end by repeating this process from step one using the same wiring scheme as the
first. If this is a Crossover cable, return to step one and continue, however,
be sure to terminate this end using the wiring scheme that you did not use for
the first end. Terminating one end with 568-B and the other with 568-A
creates a crossover.
Step
8: That's it!
Use a tester to test for continuity and you are done.
Note: If the cord does not test positive for continuity, cut the connector off and start over, or buy one of our pre-made or custom length patch cables.
