The Exfo FG-720-003M is a stand-alone remote Optical Time Domain Reflectometer (OTDR) operating at 1550 nm for continuous monitoring and fault detection in critical optical fiber networks. This unit delivers all-in-one OTDR testing and monitoring without the capital expense of a full client-server remote fiber test system. The FG-720-003M supports multiple test modes—manual, on-demand, 24/7 continuous monitoring, and scheduled intervals (hourly, daily, weekly)—with SMS-triggered testing and alert capabilities for fault conditions and resolutions.
