The EXFO PM-1623W is a dual-detector fiber optic power meter engineered for precision optical power measurements across the 800 nm to 1700 nm wavelength range. Built for demanding environments in LANs, data centers, and military/aerospace applications, this instrument delivers high-speed acquisition and field-ready performance. Dual InGaAs detectors with 3 mm aperture geometry enable simultaneous dual-channel measurements, while fast sampling rates up to 4096 samples/second per channel and 1 ms fixed-range stabilization support rapid component characterization and system troubleshooting.
