The EXFO FG-720-023M is a remote OTDR unit designed for field testing and continuous monitoring of fiber optic networks. Operating at 1310 nm and 1550 nm, it delivers dynamic range of 35 dB at 1310 nm and 38 dB at 1550 nm, enabling detection and localization of faults, splices, and reflective events across telecom, datacom, and CATV infrastructure. The unit supports multiple testing modes: unplanned manual tests with result download, on-demand testing with fault alerting, 24/7 monitoring of fault events only, and scheduled testing at predefined intervals. Real-time analysis and automatic event detection streamline field characterization workflows.
