SC Fiber Loopback
The SC Fiber Loopback is used for testing the optical performance of SC interface devices. It helps verify signal integrity in transceivers and fiber ports, making it an essential tool for network maintenance and development.
Fiber optic loopback incorporates two fiber optic connectors which are plugged into the
output and input port of the equipment respectively. Therefore, fiber loopback cables can
be classified by the connector types, such as LC, SC, MPO and MTP. These fiber optic
loopback connectors are compliant with IEC, TIA/EIA specifications.
Besides, the fiber optic loopback also can be used on single mode 9/125, multimode 50/125,
62.5/125, OM3, OM4.
The LC fiber optic loopback is one of the most popular loopbacks. support the test of transceivers
featuring LC interface. They can comply with low insertion loss, low back reflection and high
precision alignment.
