This unit

The Exfo FG-720-034L is a stand-alone Optical Time Domain Reflectometer (OTDR) designed for continuous monitoring and fault detection across single-mode fiber networks. Operating at 1550 nm and 1625 nm wavelengths, this Fiber Guardian unit delivers 45 dB dynamic range at each wavelength for precise fiber characterization. The system supports multiple test modes: manual testing with result download, on-demand testing with fault alerting, scheduled testing at user-defined intervals, and 24/7 monitoring that stores fault-related events only.

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

Aumictech offers NIST-traceable calibration and repair for the Exfo FG-720-034L. 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-720-034L 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.

Exfo FG-720-034L price

This Exfo FG-720-034L is listed at $3,420. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.

Exfo FG-720-034L calibration cost

NIST-traceable calibration for the Exfo FG-720-034L 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 →
