The Newport / ILX Lightwave FPM-8210 Series Fiber Optic Power Meter is a precision instrument engineered for high-repeatability optical power measurements across fiber optic systems and component testing. The series accommodates both connectorized and bare fiber measurements through a single input port, eliminating variability from fiber handling and orientation. Designed with exceptional polarization insensitivity, the meter delivers consistent results critical to production environments and characterization labs.
