This device comes with two female RJ-45 plugs connected to each other, in such a way that we can connect two network cables to each end. The simplest and most efficient way to splice a network cable is by using female-female adapters, which can also be called couplers. Female-female adapter: the cheapest way to splice a cable If you want to “splice” several segments of Ethernet network cables with its RJ-45 connector, it is best to buy the following adapters and devices. Methods to splice an Ethernet network cable and not lose signalĬurrently there are several tools and devices that we can use to “splice” an Ethernet network cable without losing signal or performance, we must remember that it is not recommended to “splice” the different wires within a network cable, as we have explained previously. The other way to splice a network cable and take advantage of those that we already have, without the need to make splices, would be to use adapters or other equipment as we will see below. 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.

Therefore, any cut, splice or short circuit in the cable will lead to large speed losses and even connection cuts. 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-45 plugs located at each end of the cable. 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. 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. In the hypothetical case that we need a 12-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.

Is it worth splicing a network cable while keeping the two RJ45 connectors?
