The EXFO FPM-602 is a handheld optical power meter engineered for precise measurement and characterization of fiber optic networks operating across the near-infrared spectrum. Built around a germanium detector, it delivers traceable power measurements from –70 to +10 dBm with ±5% ± 0.1 nW uncertainty and 0.01 dB resolution. The instrument recognizes over 40 calibrated wavelengths spanning 800 to 1650 nm, including critical bands at 850 nm, 1310 nm, 1550 nm, and 1650 nm, eliminating manual wavelength entry and reducing measurement error.
