The Exfo FOT-10A is a handheld optical power meter for fiber continuity testing, fault location, and loss measurement in field installations. Its compact, rugged design meets Telcordia drop-test requirements and operates over extended battery life, making it suitable for technicians deploying across multimode and singlemode fiber networks. The instrument provides direct loss measurement in dB alongside absolute power readings in dBm, with 2 kHz signal detection for fiber identification and electrical offset nulling for extreme temperature environments.
