This unit
The Exfo FTB-7600E-0034B is a single-mode OTDR module built for long-haul fiber optic network characterization. Operating at 1550 nm and 1625 nm with dynamic ranges of 50 dB and 48 dB respectively, it delivers precise fault location, splice loss assessment, and bend detection across extended fiber routes. The module achieves event dead zones below 1 m and attenuation dead zones below 5 m, enabling accurate analysis of closely spaced anomalies. With sampling resolution to 128,000 points and up to 256,000 data points, it supports distance measurements to 256 km and reflectance detection down to −70 dB.

Exfo FTB-7600E-0034B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FTB-7600E-0034B. 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-7600E-0034B 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.
