In some cases, it may make more sense to just buy a new cable. Clean it up. If the wire has an area that is mangled, cut that area out. Determine which splicing technique you will use for splicing the small usually AWG wires together.
Use a technique that you feel comfortable using. As long as there is continuity through your splice, it should work. Place a long piece of larger shrink tube on one side of the split. This shrink tube can very in length, but usually between inches will be appropriate. The length will depend on your splicing method.
Take your preferred cable strippers and cut an area of insulation that is an appropriate length for your splicing technique, from both of the cables. If there is a metal film underneath this area, you may remove this. Do not cut or nick the 8 smaller wires located beneath the insulation. Spread your 8 wires apart. If your wires have a cotton or cloth-like material between them, you may remove this as well. It is there as a padding for the wires. For each of the wires, place a piece of shrink tube, measuring approximately 3 times the length of your splice, on one side of the cut.
Damaged plug - This type of repair is very common and probably the easiest to perform. All you are doing is cutting the cable flush, stripping the jacket and re-tipping the end of the cable. Unless you are familiar with this type of work, you may want some assistance making that repair.
An RJ45 coupler is a small device, usually made from plastic, that has two female RJ45 jacks at each end. Your email address will not be published.

Why is my LG refrigerator not freezing? How much does a good dryer cost? On the other hand, if the price does not rise much and thinking about the future, perhaps you might be interested in category 7 since we have more and more routers and network cards that support Multigigabit connectivity and even 10GBASE-T.
Another thing to know before splicing a network cable is to identify the category to which it belongs. It is usually screen-printed on the cable itself and they are easy to distinguish. This would be an example of a Category 5E network cable. This is a very important factor, because when splicing a network cable, if one of them is of a lower category, it can end up losing speed.
Therefore, before you start, it is advisable to find out the category that both cables have. In the hypothetical case that we need a meter network cable and we have a 7-meter cable and a 5-meter cable, we could have the idea of joining them in a single cable. Despite the fact that some users cut the ends of the two cables and splice them, it is a practice that we should never do. The reason why we should not do it is because in many of the cases it will not work, but if at some point it does, we have a good chance of having speed, latency or stability problems.
In summary, the ideal is that a network cable is continuous, that is, it does not have cuts or splices, nor anything that can interfere from each of the RJ plugs located at each end of the cable.
Therefore, any cut, splice or short circuit in the cable will lead to large speed losses and even connection cuts. So we have two correct ways to act. One would be to choose to buy a new one of the size we need, or also to make it ourselves if we have the right tools and material.
