Connecting network cables - Does connecting cables affect the quality of the lin

Good morning,

It has an "distributed" Ethernet network on one floor of a tenement house. The cables between the main switch and individual office rooms (distribution switches) are about 200m. We are at the stage of organizing the server room, currently the cables are connected directly to the main switch, but we would like to move the cabinet. Unfortunately, the cables are too short to reach directly.

In such a situation, is it permissible to terminate the cables with sockets in the wall and connect the main switch using extension cords (patchcords?).

Do you have any experience with this type of solutions - is it used in practice or is it avoided?
Should one take into account signal losses in such a situation?
What is the failure rate for this type of connection?

200m cable? The standard says max 100m, legends sometimes mention 120m.

As for extending cables with so-called "barrels", it happened that I used such wonders, or connectors, in which the ends of two cables are split to extend them.

It is possible that I exaggerated with this length. I don't have documentation, maybe I can measure it. Generally, the cable passes from one part of the building to the other. Currently, the network works flawlessly.

How many cables do you want to extend? If, for example, 20 or more, then use the KRONE patch panel or connectors where current cables are sufficient and from here to the new cabinet longer patchcords, cables.
Couplings / barrels for 20 or more cables will take up a lot of space anyway, it will not be aesthetic to make a "big cocoon"

There are 5 cables. If they were to end in the wall, it would be necessary to extend about 5m. If it were to be "plastered", 1-2m is enough.

You actually have two options
- RJ45 barrel -


- RJ45 cable connector - present in plastic or metal housings


I used to solder a cable or "eton" connector but this is the extreme when you don't have another solution at hand.

As soon as 5 pieces you can use UY1 or UY2 quick connectors, place all cable connectors, e.g. in a cable box.
