The Opto-Electronics OFM130 is a portable optical fiber multimeter and OTDR platform engineered for field deployment in fiber optic network testing and troubleshooting. This single instrument integrates optical power measurement, integrated light source, and visual fault location into one compact device. It performs fiber continuity verification, optical power measurement, and fiber break identification across both single-mode and multi-mode fiber types.
