12 Fibers MPO OM4 Multimode Fiber Loopback Module

12 Fibers MPO OM4 Multimode Fiber Loopback Module

The 12 Fibers MPO OM4 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 a 12-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 OM4 50/125μm laser-optimized multimode fiber and precision MPO connectors, this fiber loopback module provides stable optical performance and reliable repeatability for 850nm high-bandwidth multimode transmission systems. Its compact plug-and-play design makes it suitable for QSFP, QSFP+, QSFP28, data center switches, routers, optical transceivers, test equipment, burn-in 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.
