This unit
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.

Exfo FG-720-023M — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FG-720-023M. 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-720-023M 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-720-023M price
This Exfo FG-720-023M is listed at $9,260. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
Exfo FG-720-023M calibration cost
NIST-traceable calibration for the Exfo FG-720-023M 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 →
