Fiber Loopbacks

Sorry, no canvas available

Camplex's CMX-LB Series of Fiber Loopback testers are precision testing tools designed for validating optical network equipment and troubleshooting fiber optic systems. By creating a closed-loop connection between transmit and receive ports, these modules enable technicians to verify signal integrity, diagnose link failures, confirm proper equipment operation without requiring a remote connection, and extend signals through patching.
