Exfo FG-720-034U 1550, 1625 OTDR

The EXFO FG-720-034U is a dual-wavelength OTDR engineered for field detection and monitoring of fiber optic network events across 1550 nm and 1625 nm bands. Built for live fiber analysis and OSP environments, it delivers 50 dB dynamic range at 1550 nm and 48 dB at 1625 nm, enabling precise identification of splices, bends, and faults. The unit operates in multiple modes—manual, on-demand, 24/7 continuous monitoring, and scheduled testing (daily, weekly)—with configurable alert thresholds and SMS fault notifications.

With 80 GB local storage protected by RAID configuration, the FG-720-034U stores comprehensive trace data and fault events. Network connectivity via 10/100/1000 Base-T Ethernet (IPv4/IPv6) enables web server access from any standard browser, supporting both local LAN and remote WAN management. Power flexibility spans 100–240 VAC (50/60 Hz) or -40 to -72 VDC. The platform integrates with EXFO’s NQMSfiber system for centralized network operations and automated event detection, scaling across multi-site deployments.
