FAQ
The MTRJ Multimode Fiber Loopback Cable is designed for optical network testing and diagnostics by looping transmitted signals back into the receiving channel. It enables fast verification of transceiver ports, link integrity, and equipment performance in multimode fiber systems.
Built with 62.5/125μm OM1 multimode fiber, this loopback cable is suitable for legacy Ethernet and short-distance optical communication systems. The MTRJ duplex connector provides a compact, dual-fiber interface in a single push-pull housing, making it ideal for high-density testing environments where space and quick installation are important.Loopback Modules Choosing Guide
