LC Fiber Optic Multimode Loopback Adapter LC Optical Loopback
Testing Cable
Description of Fiber Optic Loopback
Loopback used for testing the system or network system in the
signal back, through the return signal, you can detect the network
link in a variety of potential anomalies, this test is widely used
to ensure the normal network link to provide An effective detection
method. Fiber Optic Loopback Modules may also be used for the
burn-in stage of boards and other equipment.Loopback Modules
incorprate two fiber optic connectors. One fiber optic connector is
plugged into the output port, while the other fiber optic connector
is plugged into the input port of the equipment.
