This unit
The Exfo FTB-7534B OTDR module delivers optical time-domain reflectometry at 1550 nm and 1625 nm wavelengths for single-mode fiber characterization. This field-interchangeable module performs installation verification, maintenance diagnostics, and rapid fault isolation across distances to 260 km. Four-point loss measurements, splice and connector detection, optical return loss calculation, and event characterization support comprehensive network analysis in long-haul and ultra-long-haul deployments.

Exfo FTB-7534B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FTB-7534B. 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-7534B 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.
