Hello everyone,

I hope my question(s) here are not too network-specific, otherwise I would probably have to turn to an IT forum. But I'll try here first.
We recently acquired a new building and after various to-do points, the topic of the network is next on our agenda.

Unfortunately, in my opinion, the builder did not think very far regarding this. "At least" there is one double LAN socket on the ground floor and one on the upper floor. In the utility room, where the fiber optic modem is now hanging, two CAT.7 patch cables come out of the wall, which unfortunately still do not have connectors at the end. I assume they come from these two sockets.

Originally, I wanted to crimp both cables after doing some research. However, I do not know according to which standard the network sockets are wired - EIA/TIA-568A or 568B. I took a photo - can you already tell from the visible colors? Although I have to say, to me as a layman, it looks like the wiring is generally wrong. In neither of the two standards is orange on the very outside, right?

It is also noticeable that apparently only one of the two sockets is connected each time (actually logical, with only one cable each). Now I am considering going with one cable to both sockets, at the cost of only having a max of 100 MB/s. That should be possible, right?

In Europe, TIA-568A is usually used. However, in principle, it doesn't matter as long as you do it the same way everywhere. Nothing can be recognized from the photo. If the visible colors are supposed to be PIN 1-4 or 5-8, it would be neither of the two standards, because in both green/green-white or orange/orange-white do not appear in this order. Just open the socket and check which PIN has which color.

Splitting is possible, but why would you do that? Depending on your needs, it's better to just add a small switch, which also comes with power supply via PoE, meaning you could power it via a PoE switch in the connection room.

Above all, you then set up a small gigabit switch that offers not only more ports but also more bandwidth.

Take the can out completely and first have a look at what is connected there.

As already mentioned, remove the box and see how the cables are arranged.

In the utility room, do not crimp plugs onto the cables; instead, fixed wiring is used for installation cables. If there are only two cables, the easiest solution is to use a double network socket.

It actually can't be 568A based on the colors. But who knows what kind of specialist worked on it... I'm with and
