Make a Cat6 Patch Cable

These steps outline how to make your own Cat6 patch cable. These steps can also be used on Cat5 and Cat5e cable. Note that Cat5 and Cat6 cable have their own ends.

Required tools:
- A length of Cat6 cable
- Two Cat6 cable ends
- Crimping tool
- Cable jacket stripper (sometimes it's part of the crimping tool)

Optional tools:
- Rubber snagless boots
- Plastic pinout aligners
- Cable tester

1.

Gather your materials

Grab your spool of cable, end, crimping tool, jacket stripper, and other optional tools.

2.

Cut a length of cable

Hopefully you measured before you cut a length for production use. I always cut an extra few inches over what I measure, because I usually end up needing more than what I initially measure for some reason. Also, leave yourself an extra few inches if you aren't a seasoned cable maker, it will give you the extra cable you will need in case you mess up crimping or aligning.

Most crimping tools can cut cable.

(Optional) Put snagless boots on

If you have the rubber snagless boots, put one on each end of the cable.

4.

Strip cable jacket at the ends

Use your cable jacket stripper, or your crimping tool if it has one, and strip about 3/4 of an inch of jacket on each side, exposing the 8 smaller wires.

Aligning cables 1

Separate the four pairs in the center.

6.

Aligning cables 2

Untwist each pair. Try to keep as much of the cable twisted as possible for performance reasons.

7.

Aligning cables 3

Arrange the cables according to the pinout diagram. The order from left to right should be:

Orange - White
Orange
Green - White
Blue
Blue - White
Green
Brown - White
Brown

A good technique is to line up the orange on the left, brown on the right. Split the green and move the GW to the left, and G to the right. Then, untwist the blue and keep them in the center.

8.

Clip uneven ends

At this point, I usually clip the ends of the cables to make them even.

(Optional) Put plastic pinout aligner on

If you have a plastic pinout aligner, put it on.

10.

Insert cable into end

With the cables still aligned, insert the cable into the RJ45 connector. You will want to hold the connector so the gold pins are facing you, and the cable order is still OW-O-GW-B-BW-G-BrW-Br from left to right.

Make sure the jacket is far enough in the end to be caught by the clip when crimped. Also, check the front of the cable; make sure you can see the copper ends of the cables.

11.

Crimp the end

Insert the end into the crimping tool. Make sure the cable is still fully inserted into the end, and the end is fully inserted into the crimping tool. Squeeze the crimping tool with enough force to push the pins into the copper, and push the clip into the cable jacket. The amount of squeezing force will differ with each crimping tool.

Afterwards, you can check the crimp job by tugging on the end and the cable. Don't try to muscle it off of there, but make sure it can hold if caught by a user and tugged on.

(Optional) Slide the snagless boot over the end

If you put a snagless boot on the cable, slide it over the cable end.

Other end

Follow steps 5 through 12 for the other end.

 
14.

Cable test

Plug both ends into your cable tester, make sure all appropriate LEDs light up. I recommend jiggling the ends and cables around while plugged in to make sure the cables are crimped properly.

If you don't have a cable tester, plug a piece of equipment into a switch with the cable, and make sure you can access the network without issues. You can try something like running a continuous ping while jiggling the cable around on both ends.

Conclusion

This patch cable can be used to connect OSI layer 2 devices to layer 3 devices, such as PCs to switches, and switches to routers. These steps don't take into account spacers that may be present in Cat6 cables.
