Hi, we all know about the Loopback adapters for RJ45 Connectors. With them, you can get an interface up without having a real link on it. Might be useful in some cases.

I need such an adapter and want to buy it from a distributor. But they are not mentioned anywhere.

I remember there was another name for such kind of adapter, do you know about it? Or where can I buy it?

If you want to do this for a LAN interface you need to wire pin 1 to 3 and pin 2 to 6.  Leave all other wires disconnected.

For 10/100 Mbps connections craigbeck is correct.

If you want to test 1000 Mbps you still use 1-3, 2-6, but then you also need 4-7 and 5-8.

Typically they are not sold becuse they are so easy to make.

Also if it helps Windows has virtual loopback adapters which you can install - just in case you don't need a physical plug.
