WG OLS-25 , OLA-35 , OLP-1 OPTICAL METERS FULL SET W CASE

The WG OLS-25, OLA-35, and OLP-1 Optical Meters Full Set is a three-instrument kit for fiber optic network characterization and testing. It combines an optical light source, variable attenuator, and power meter in a single portable package with carrying case. Field technicians and network engineers use this set to measure signal loss, continuity, and power levels across single-mode fiber installations.
