Electrical planning - Is one data socket enough?

Hello,

I had the same question last year and then I inquired.
I decided on a simple network socket because with it I can use the full bandwidth (also depending on the network cable) of 1 GBit and do not have to share it. If I want to connect multiple PCs, I simply connect a GBit switch behind it if necessary.

Hope that helps you.

Best regards

Hello, I also had to deal with this

and 2 network technicians independently confirmed to me that the bandwidth has nothing to do with the single - double decision. According to them, double sockets are already installed by default to be more flexible.

For a 1,000 MBit transmission, the cable is primarily decisive: Either old CAT 5 e cable (but it must say "1,000 MBit" on it!) or better the CAT 7 cable. CAT 7 is definitely gigabit-capable. However, at the latest when it really comes to gigabit, the expensive special MBit sockets should also be used. The normal sockets are usually only up to CAT 5 and basically degrade the CAT 7 to 500 MBit. In my opinion, this has nothing to do with the single - double question.

I currently lay 2 CAT 7 cables to each socket and use the normal CAT 5 sockets, but double. If I ever have gigabit, I only have to change the sockets, the cable can remain.

Why are you laying the Cat7 cable twice to each outlet? So that you don't halve the performance? Or for what reason are you doing it this way?

A network cable has eight conductors (4x2). To make a network connection (1 port) gigabit-capable, all eight conductors of the network cable must be terminated. Whether Cat5e/6 or 7 is used only matters for longer distances. For a 100Mbit network, only 4 conductors per port are sufficient. Therefore, with a double socket, two 100Mbit connections can be made with just one cable. It depends on the connection and not necessarily on the cable. For a gigabit network, two cables must be laid to a double network socket.
