Exact definition of loop-back plugs will depend on what application we are talking about. Mostly these are connector plugs with a metal inside to short two electrical signals. There can be loopback plugs for different applications. These can be for a serial port or an Ethernet port or loopback plugs for specific signals on a connector or on a printed circuit board. These are very useful for debugging and testing an electronics problem. E.g. one can do a loopback on PC serial port's Transmit and Receive (Tx and Rx) lines using a loopback plug or a metal short to see if the serial port is working fine. Similarly Ethernet ports can be tested with a loop-back plug made for the purpose. - Neeraj Sharma

What are the difference between local loop back testing and remote loop back testing?
The only difference is the relative location of the device that is in loopback mode. Local loopback testing is when your device is set to send back everything it receives to the sender, aka loopback mode. Remote loopback testing is when your device orders a foreign device to enter loopback mode.
