Exfo FG-720-034M 1550, 1625 OTDR

The EXFO FG-720-034M is a dual-wavelength stand-alone remote OTDR unit engineered for testing and monitoring optical fiber networks at 1550 nm and 1625 nm. Deployed as an autonomous Fiber Guardian device, it performs continuous or on-demand diagnostics without requiring external servers or client PCs. The unit delivers dynamic range of 38 dB at 1550 nm and 36 dB at 1625 nm (measured at 3-minute averaging, 20 µs pulse width, SNR of 1), making it well-suited for metro and FTTx network troubleshooting.
