Fiber Optic Loopback Module as called Optical Fiber Loopback, OPELINK's Fiber Optic Loopback offers a simple and effective way to test the functionality of optical network devices with very low loss characteristics.
Description Parameters Company Profile Related Product
Fiber Optic 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.
LC Duplex Multimode Fiber Optic Loopback Module
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
