This unit
The Exfo FTB-7503B is a 1550 nm OTDR module engineered for long-haul fiber optic network characterization and fault detection. Operating as an interchangeable component within EXFO's FTB test platforms, it delivers ultra-long-range measurements to 260 km with fast acquisition and precise event localization. The module combines high dynamic range performance with field-portable deployment capability, making it ideal for long-distance link commissioning and troubleshooting across carrier and enterprise networks.

Exfo FTB-7503B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FTB-7503B. 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 FTB-7503B 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.
