    Hello
    How to connect a cut network cable? It was in the wall and I accidentally cut it? Is there any cube or soldering involved? Or do you need to replace the whole thing?

    greetings

    In my case, there was an intersection on the 70M cable. I soldered and it worked ok. If you have the cable in your apartment, it would be good if you did not tape everything after soldering because of the moisture which then causes the signal to be attenuated. Another solution is to install two RJ-45 cubes and a special plug for connecting such cases, but by soldering cheaper. Good luck.

    the cable is in the apartment and will be plastered, so it's better not to wrap it with insulation? What if I applied (I don't know what exactly is called) thermal insulation?

    seriously, don't solder these wires. it's not worth it. the problem may also be the losses in this cable. not quite soldered, the twisted pair may not work properly

    basman123 your idea is definitely better, more simple to implement. but I have to do it today and I don't know if I will get something like that in Olsztyn :cry:

    Don't look at it, solder and insulate it. She will be fine, unless your section is over 100m. Just try to get the steam up as little as possible. After you solder and insulate, twist them again. Just don't confuse the pairs, because then there may be problems.

    I have a network pulled on a twisted pair from a friend and there is about 120 meters of cable and everything works fine and the cable has already been damaged twice and once completely cut because my friend is renovating the house. I took the soldering iron in my hand thermal shirts and after precision soldering the pairs and twisting them again, everything works as before, so do not play with any connectors, just solder the damaged pairs and insulate and then plaster and there will be no problem ...

    It's a pity for the money for anything. as for plaster, secure it. They may be heat shrinkable tubing.

    and that is a very good solution :)

    In Olsztyn, today you will get such a good thing, for example, in an electrician, I don't know about a metal one, in this shop with dupes for electricians.

    I really recommend this solution because:
    - the scotchlok has a gel inside and this prevents the ingress of water, air, etc. So the cable is not snowy
    - it is simple to use and works like a clamp
    - is cheap

Topic summary

To connect a cut LAN network cable, users have several options. Soldering the wires is a common method, but caution is advised as improper soldering can lead to signal loss. It is recommended to twist the pairs back together after soldering and insulate them properly to prevent moisture ingress. Alternatively, gel-filled crimp connectors, such as Scotchlok, can be used for a moisture-resistant connection without soldering. These connectors are easy to use and provide a reliable seal. Users should ensure that the cable length does not exceed 100 meters to maintain signal integrity. Overall, both soldering and using connectors are viable solutions, with a preference for connectors in moisture-prone areas.
