This unit
The EXFO FTB-7403B is a 1550 nm OTDR module engineered for single-mode, long-haul optical fiber characterization and fault detection. This field-interchangeable module delivers precise fiber event identification, attenuation measurement, and distance-to-fault localization across extended cable routes. Designed for installation, maintenance, and troubleshooting of optical communication networks, the FTB-7403B integrates into EXFO's portable test platforms to enable rapid field diagnostics with high repeatability.

Exfo FTB-7403B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo FTB-7403B. 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-7403B 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.

This Exfo FTB-7403B is listed at $1,330. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
Exfo FTB-7403B calibration cost
NIST-traceable calibration for the Exfo FTB-7403B is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument 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. Turnaround is 1 to 3 business days after receipt. See full calibration details →
