Fiber Optic Loopback Modules
This page lists all of our loopback cable products for fiber testing applications. Also known as a loopback adapter or loopback plugs, this network equipment works by connecting adjacent pairs of network ports. The resulting loopback signal makes it easy to perform a fiber optic loopback test on fiber wires and equipment. We carry both singlemode and multimode loopback plugs and we have a variety of loopback testers for different connector types in order to make sure any kind of network is working as intended.
