This unit
The EXFO FTB-7500E is a OTDR module engineered for fiber characterization in metro and long-haul networks. It delivers accurate fault location, splice analysis, and network health assessment through advanced bidirectional testing and real-time measurement capabilities. The module integrates with EXFO's portable FTB platform family, enabling field technicians to perform comprehensive optical fiber diagnostics across multiple distance ranges and wavelengths.

Exfo FTB-7500E — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FTB-7500E. 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-7500E 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.
