How to connect 2xRJ45 sockets to one cable?

Question

Hi, can 2 RJ45 sockets be connected to one cable as shown in the photo? Cat6 cable and sockets. I will add that I checked the entire network with a tester and the signal passes through every point without any problems, the only question is whether the Internet has the right to work on it at all and if so, what speed limits could be expected?

If you want two sockets, there must be two wires or install a switch. Another option is to split the cable into two sockets, but then the maximum speed is up to 100Mb/s.

1. With such a connection, Cat.6 remains a memory. How much less it will be is unpredictable.

2. It would work better or worse if you connected anything ONLY to one of the sockets - the second one would have to be unconnected . As you can see, two sockets in such a system would be pointless, so it would be best to replace them with one and have cat.6.

3. Or, alternatively, as @sosarek wrote, separate the cables and connect two pairs to each socket. Of course, you would also have to unplug the other end of the cable in the same way. Then you would have up to 100Mbps on each socket.

Thank the electrician or yourself...

I thought it wouldn`t work the way I wanted it to. The Internet will be 1Gb, so there is no point in limiting yourself to 100Mb, so I only have to run a second cable. Thanks for the answer

It depends on what you connect to these sockets - because all RTV equipment usually has 100Mb/s eth cards, so it is enough for them (this is sometimes done if you lack sockets in a given point). 1GB is only for computers and NAS.

Your friend is right, but cables are more difficult to replace than devices. I wanted to write that today there are 100 cards and tomorrow there will be 1000. If it were me, I would add a cable while it was possible.

Exactly - if it is possible to add a cable (1 or 2 pieces), this is the only option.

One more note - the wires are undone for far too long. This may (but does not have to) cause problems in the operation of the network, and certainly in obtaining the connection parameters required for category 6. For category 6, the furcation is a maximum of approximately 5 mm.
