How to Make a Network Cable
First strip the jacket from the cable, being very careful not to cut into the individual conductors. It is wise to take a few practice tries to make sure you are not stripping too deep before you end up cutting too much off.
The four twisted pairs.
Next untwist the pair to make them workable. Try not to untwist to far as the twisting helps eliminate crosstalk and provides for a better quality cable.
Next, arrange the eight conductors according the 568b wiring specifications.
This next step can take some practice. Trim back the conductors so they are all very close in length. Your goal is to cut them just long enough to insert into the RJ-45, and no longer.
Sometimes it helps to press all 8 conductors against the back wall of the inside of the RJ-45 with your thumb while sliding them into the connector.
Notice how the conductors themselves are as short as possible in the picture below. This will minimize crosstalk, as they are twisted as much as possible. Also notice the grey jacket is pushed up as far as possible. When crimped, the RJ-45 will grab the jacket of the cable and this will provide for a strain relief. This is an important step in building a cable that will last.

- Dish Network vs. Cable
It is not possible for us to directly compare Dish Network satellite service to cable television service, because each cable television company offers different programming packages, pricing, and service levels. This guide will help you to compare Dish Network with the cable television which is available in your area. Pricing Dish Network competes in an [...]...
- How to Use Cable Splicing Tools
Cable splicing tools are a fast and effective way to connect two wires or cables into one. Most cable splicing tools look like pliers; however others are more like scissors or utility knives. Here are some tips on how to best use these cable splicing tools: For Larger, Thicker Cables First, the type of splicing [...]...
- Cable Ties
A cable tie, also commonly called a zip tie, is a length of strong Nylon lined with a gear rack. On one end of the tie is a small square case through which you can feed the other end of the tie. The teeth on the tie are arranged in a saw-tooth pattern, and the [...]...
- Plenum Cable
The plenum is hidden space within a building which is used for HVAC (Heating, Ventilation, and Air Conditioning) and to run cables. Plenum space is normally above a suspended ceiling or under a raised floor. Buildings without plenum spaces will have cabling and HVAC ducts within plain view. The plenum space is normally used to [...]...
