Hello everyone,
I want to clarify that I am a novice in networking and telecommunications...
I'm doing some work at home and I'm changing the location of 3 RJ45 jacks in my room (moving them 2.1m from my outlets and my box). They are all independent of each other.
I've managed to remove the conduits in my attic and I need to extend 2 of the 3 cables in order to move my outlets.
While thinking about how to extend my RJ45 cable, the following question comes to mind: Is it possible (for aesthetic reasons) to group my 3 RJ45 cables in my attic using a specific box for this purpose? This would allow me to pull just one extension and have only one RJ45 socket visible in my wall.
I made a diagram to facilitate understanding of my problem :D
If that is not possible, what type of connector would you recommend for extending an RJ45 cable? (I want to specify that the ends of my cables do not have plugs and it is just the 8 colored wires that appear).
Thanks in advance.

Hello,
Yes, it's called a Switch!

(You usually need a 230v power supply, but if that's not possible, there are alternatives)
Best regards.

Hello,
As T3chN0g3n mentioned, we can use a switch, one line coming from the box, and three lines going to the devices.
But be careful with the cables and sockets. Normally, in the walls, we have single-strand cables with female sockets (wall-mounted or patch panel) at each end. The male/male cords are made with multi-strand cables.
To have a male RJ45 socket on a single-strand cable, you need to use special sockets, known as construction sockets or field sockets.
See: https://forums.commentcamarche.net/forum/affich-37585049-compatibilite-cables-et-prises-rj45
Alternatively, in the attic, you can install four patch panel sockets (female) with a small box at the end of the cables from the wall sockets and connect these sockets to the switch with Ethernet cords (male/male).

Thank you for your quick feedback.
The first difficulty I will have is that my grouping of 3>>>1 is taking place in the attic. I don't have a power supply at that location, so there's no possibility for such a box that requires power. What would the alternative be then?
This kind of tool wouldn't work: https://www.leroymerlin.fr/produits/electricite-domotique/reseau-informatique-et-telephonie/cable-ethernet-et-accessoires-informatiques/cable-ethernet-rj45/raccord-rj45-femelle-2x-rj45-femelle-83147221.html?
The second remark regarding yours, Jee pee, indeed as for the setup
3 independent RJ cables so 3 MALE PLUGS AT EACH END --- GROUPING BOX --- MALE PLUG then 2 M CABLE then FEMALE PLUG at the wall outlet.
Therefore, I would need to buy male RJ 45 connectors and crimp them onto my bare cables (3 at the entrance of the box + 1 at the exit).

No, the splitter you linked will not work.
You can use the RJ45 cable to power a so-called "PoE" (Power over Ethernet) switch, but you need an injector in addition (to be installed at the output of your box, for example), unless the box has a suitable port, which is not very common.

Thank you for these explanations.
I think I'm going to give up, it brings more constraints/costs than anything else. I will compromise and go for double Ethernet sockets (https://www.manomano.fr/prise-rj45-composable-2191?model_id=14971777&referer_id=698395&gclid=EAIaIQobChMIlcqG14bm9QIVDRkGAB1eKQaCEAQYAyABEgKwJPD_BwE%29, this will allow me, with the 3 RJ45 sockets, to have only 2 outputs instead of 3 (one double + one single)
To extend the cables, do you think this type of equipment is suitable?

The initial problem was having only one output block out of the three; with the double socket, I would have two.
However, I called a supplier who told me that a coupler to extend the cable could potentially cause a lot of interference and therefore may not be relevant. I'm not sure what to think about it, and I’m annoyed at the idea of removing the entire length of cable.

You won't know if extending the cables works without testing. But in principle, it's the same as putting a female socket and a male socket between the two cables. However, removing a cable would be better. Plus, with the new one and the old one stuck together, by pulling on the old one you bring the new one along.
There are triple wall sockets: https://www.conrad.fr/p/prise-reseau-encastre-insert-avec-plaque-centrale-et-chassis-cat-6a-3-ports-metz-connect-1309131002-e-blanc-pur-972563?t=1&utm_campaign=feed&utm_content=&utm_medium=comparison&utm_source=kelkoo&utm_term=972563

Hi,
is all this just to move the box 2m?
Personally, I would have just used longer cords to reach the box.
Unless the partition with the outlets is going away?

Thank you for your feedback, I’m going to completely change the cable. I don't think the salesperson wanted to sell me cable, he has feedback from a client who used this method, and apparently the connection wasn't great... And in terms of cost, 15 meters of cable or connectors + 2-3 meters should come out to about the same.
I didn’t think Ethernet sockets existed in triples. Besides, I’m a bit of a perfectionist, I already have a brand of sockets and switches... It looks messy to have sockets of different brands (especially since I'm renovating the room, might as well make it look neat ^^).
Finally, for the last reaction, I suspected I'd have someone with a sharp sense of criticism :D :D And yes, all this for 2 meters but it’s related to the position of my fiber box. The technicians placed it at the other end... It makes me run the box across the entire length of the wall with the fiber cable (yes, there are wire covers above the baseboards but I don’t want to hear about that either).
