Description:
Fiber Loopbacks are also called optical loopback adapters. They are designed for testing, engineering and the burnin stage of boards 
or other equipment. Optical loopback adapters provide system test engineers a simple but effective way of testing the transmission capability
and the receiver sensitivity of network equipment.


Features:
1. Fiber Loopback Module provides a media of return path for a signal, whether the signal is for testing purposes or due to network restoration
2. In the case of testing, the loopback signal is used for diagnosing a problem
3. Sending a loopback test to a network equipment, one at a time, is a technique for isolating a problem
4.The fiber G657.A1 ,G657.A2 Can be chioced. 0.9mm or 2.0mm

Application:
R&D
Fiber labs
Telecom testing
FTTX testing
Equipment interconnection
Device pig-tailing 
Premise networks
Patch panel applications
Communications connections
Loopback for network components testing
