Fiber Optic Loopback

Fiber optic loopback are designed for testing, engineering and the burn-in 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. One connector of fiber optic loopback is plugged into the output port, while the other is plugged into the input port of the equipment. When used in testing applications, loopback signals are used for diagnosing problems. The best practice is to send a loopback test to network equipment, one at a time for isolating the problem. Common fiber optic loopbacks types are: SC fiber optic loopback, LC fiber optic loopback, MT-RJ fiber optic loopback.
