The EXFO FPM-602X is a handheld optical power meter for precision measurement of optical signal power across fiber optic networks. Optimized for the 800 nm wavelength and equipped with a high-power Ge detector, this instrument delivers accurate power analysis from +26 dBm to -55 dBm. It supports over 40 calibrated wavelengths spanning 800 nm to 1650 nm, including critical PON wavelengths at 1310 nm, 1490 nm, and 1550 nm compliant with ITU-T G.983 and G.984 standards. The meter features 0.01 dB resolution, user-configurable pass/fail thresholds with LED indication, and automatic wavelength recognition when paired with compatible sources. Built for field deployment, the FPM-602X includes tone detection at 270 Hz, 1 kHz, and 2 kHz; offset nulling for temperature and humidity compensation; and Min/Max power capture for burst analysis. A 1000-item data memory enables on-site logging with USB export capability. Operating on a rechargeable battery with 72-hour typical runtime and auto-shutoff, the meter measures 190 mm × 100 mm × 55 mm and weighs 480 g, supporting FC and SC connectors with optional adaptors.
