8 Fibers MPO OS2 Single Mode Fiber Loopback Module

8 Fibers MPO OS2 Single Mode Fiber Loopback Module

The 8 Fibers MPO OS2 Single Mode Fiber Loopback Module is designed for testing, troubleshooting, and burn-in applications in high-density single mode fiber optic networks. It routes the transmit channels back to the corresponding receive channels through an 8-fiber MPO interface, allowing technicians to verify parallel optical transceiver performance, equipment port functionality, and link stability without connecting to an active fiber network.

Built with OS2 single mode fiber and precision MPO connectors, this fiber loopback module provides stable optical performance, low insertion loss, and reliable repeatability for single mode parallel transmission systems. Its compact plug-and-play design makes it suitable for QSFP, QSFP+, QSFP28, QSFP-DD, switches, routers, test equipment, and other high-density MPO interface devices. Custom fiber count, polarity, connector gender, connector type, housing color, and labeling options are available upon request.
