The EXFO FOT-20A Handheld Power Meter measures optical power and fiber-link loss in field environments with ±0.05 dB resolution and NIST-traceable accuracy. Designed for technicians installing and maintaining LAN and fiber-optic networks, the FOT-22AX-SPC and FOT-22AX variants deliver direct loss measurements, transmitter power analysis, and component insertion-loss testing across five electronically calibrated wavelengths. Linear amplification technology ensures long-term calibration stability. Electrical offset nulling supports operation across extreme temperature conditions without drift.
