What Does Wrap Plug Mean?
A wrap plug is a special connector that is designed to perform a diagnostic test called a loopback test. It is inserted into a port on a communication device and crosses over to the transmission line from the receiving line so that the outgoing signals can be looped back to the computer for testing. The wrap plug can determine whether a device is in working order or has properly functioning nodes in the network. It can also be manufactured for specific tests and systems, or used as an attenuator to stimulate the path loss in an actual communication circuit. A wrap plug causes the output signals to be returned as input signals so that a complete communication circuit is roused. In order to obtain accurate test results and avoid damage to the equipment during testing, the manufacturer’s guidelines must be thoroughly followed.
Techopedia Explains Wrap Plug
A wrap plug is a special connector that routes digital data streams or electronic signals from their origin back to the source without deliberate changes or processing. It is largely designed and intended for testing transmission infrastructure called a loopback test. The loopback test can consist of four different types:
