The ILX Lightwave FPM-8210 is a fiber optic power meter engineered for accurate optical power measurements in production test and characterization environments. It delivers high repeatability and exceptionally low polarization-dependent response across a broad wavelength range. The instrument accommodates both connectorized and bare fiber inputs through a single port, with extended measurement zone capabilities for bare fiber applications.
