This unit

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.

Exfo FG-720-034U — Repair & Calibration Service

Aumictech offers NIST-traceable calibration and repair for the Exfo FG-720-034U. Calibration covers distance accuracy verified against a calibrated fiber length reference, event loss measurement accuracy at splice and connector events, dead zone (event and attenuation) at rated pulse width, dynamic range verification at 1310 nm and 1550 nm, backscatter coefficient calibration, and return loss measurement accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.

Common Exfo FG-720-034U faults: optical port connector damage or contamination, battery failure, display damage from field use, module failure on FTB or MTS platforms, calibration drift. Most field OTDRs fail due to physical damage. On modular platforms (EXFO FTB, Viavi MTS), individual module failures are serviced without replacing the entire mainframe. Optical port cleaning resolves many apparent measurement faults before mechanical repair is needed.

This Exfo FG-720-034U is listed at $7,080. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.

Exfo FG-720-034U calibration cost

NIST-traceable calibration for the Exfo FG-720-034U is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers distance accuracy verified against a calibrated fiber length reference, event loss measurement accuracy at splice and connector events, dead zone (event and attenuation) at rated pulse width, dynamic range verification at 1310 nm and 1550 nm, backscatter coefficient calibration, and return loss measurement accuracy. Turnaround is 1 to 3 business days after receipt. See full calibration details →
