SuperLooper Ethernet Loopback Jack & Plug

The SuperLooper™ Ethernet Loopback Jack and Plug quickly and easily checks the RX/TX pairs of 10/100base network cables, helping a network technician determine if a network signal exists or if there are broken or shorted wires within the cabling (See Specifications). It can be plugged directly into an Ethernet wall port or can be attached to the end of a network patch cable.
