This unit
The EXFO FTB-7323B is a single-mode OTDR module engineered for precise fiber characterization and network troubleshooting. Installed within an FTB series mainframe, it delivers fault location, event detection, and loss measurement across dual wavelengths with sub-meter sampling resolution and minimal dead zones. The module achieves 90% dynamic range in under 30 seconds and initiates trace acquisition in as little as 7 seconds.

Exfo FTB-7323B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FTB-7323B. 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-7323B 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.
