The fiber loopback module is designed to provide a media of return patch for a fiber optic signal. Typically it is used for fiber optic testing applications or network restorations. For the testing applications, the loopback signal is used to diagnose a problem. Sending a loopback test to network equipment, one at a time, is a technique for isolating a problem.
Fiber loopback modules can provide an economical solution for many fiber optic test applications.

Customized Duplex LC/SC PVC (OFNR) Fiber Loopback Module
Customized Duplex LC/SC Fiber Loopback Module
OM1/OM2/OM3/OM4 Multimode
Internal Configuration
Equipped with a LC/SC Loopback cable inside, it supports the test of transceivers featuring LC/SC interface.
External Configuration
Equipped with a black enclosure to protect the optical cable, and the looped space is reduced for an easier usage and economic package.
Dustproof Function
Every Loopback Module is equipped with two small dust caps, which is convenient to protect it from pollution.
Energy Saving
Complying with the RJ-45 style interface. Having a low insertion loss, low back reflection and high precision alignment.
Fiber optic loopback modules incorporate two fiber optic connectors and they are plugged into the output and input port of the equipment respectively so that a signal can be sent from a communication device and looped back to the device as a way to troubleshoot a defective node in the network.
