cat6socket -> cat6 cable (solid core) 10 meters long -> cat6 socket.
What are those sockets? A lot of sockets have built in transformers and termination resistors.
Only the sockets for devices do this. The sockets for wall sockets and patch panels are pure connectors, since they aren’t endpoints.
One common exception is sockets intended for phone use. Even if they're 8p8c / RJ45 (insert argument about naming here). The patch panel shouldn't have any of that, but the wall socket might.
OK, I did a bit of googling and found some cases where the whole jacks (as in, the wall box) can contain a component: primarily ISDN jacks with built in terminators. ISDN does require terminator resistors on the last socket on a line. But in every example I saw, this was part of the whole wall box, not inside the actual connector itself. (E.g. it's a plain 8P8C connector, with punchdown blocks and the resistor, all on a PCB.) I also saw some British jack boxes with built in spark gaps or surge arrestors, resistors and ring capacitors. But again, on a PCB, not integrated into the connector itself. (I've never seen this anywhere else; I think elsewhere, it was normal to have these components inside the telephone itself.)
But this thread is about Ethernet patch panels. The Cat 5/6/7 sockets used for wall jacks and in the patch panels MUST be purely passive, as I said. They're nothing but extension cords. The actual Ethernet endpoints are in the devices that are connected through the wall wiring.
