8 Fibers MPO OM3 Multimode Fiber Loopback Module

8 Fibers MPO OM3 Multimode Fiber Loopback Module

The 8 Fibers MPO OM3 Multimode Fiber Loopback Module is designed for testing, troubleshooting, and burn-in applications in high-speed multimode 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 optical link stability without connecting to an active fiber network.

Built with OM3 50/125μm laser-optimized multimode fiber and precision MPO connectors, this fiber loopback module provides stable optical performance and reliable repeatability for 850nm multimode transmission systems. Its compact plug-and-play design makes it suitable for QSFP, QSFP+, QSFP28, switches, routers, data center equipment, test systems, and other high-density MTP®/MPO multimode interface devices. Custom fiber count, polarity, connector gender, connector type, housing color, and labeling options are available upon request.
