OS2 Single Mode SC/APC Fiber Loopback Module

OS2 Single Mode SC/APC Fiber Loopback Module

The OS2 Single Mode SC/APC Fiber Loopback Module is designed for optical transceiver testing, network troubleshooting, and burn-in applications in single mode fiber optic systems. It loops the optical signal from the transmit port back to the receive port, allowing technicians to verify transceiver performance, equipment port functionality, and optical link stability without connecting to an active fiber network.

Built with OS2 single mode fiber and SC/APC connectors, this fiber loopback module provides stable optical performance, low insertion loss, and low back reflection for 1310nm and 1550nm single mode transmission systems. The standard SC interface offers secure mating and easy handling, while the angled APC polish helps control return loss in applications where reflected signal performance is important. It is suitable for switches, routers, media converters, optical transceivers, test equipment, and other SC/APC interface devices. Custom fiber type, connector polish, wavelength, housing color, and labeling options are available upon request.
