16 Fibers MPO OM3 Multimode Fiber Loopback Module

16 Fibers MPO OM3 Multimode Fiber Loopback Module

The 16 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 a 16-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 high-speed multimode transmission systems. Its compact plug-and-play design makes it suitable for QSFP-DD, OSFP, 400G/800G multimode optical modules, data center switches, routers, test equipment, and high-density MTP®/MPO multimode interface devices. Custom fiber count, polarity, connector gender, connector type, housing color, and labeling options are available upon request.
