This unit
The Yokogawa AQ7286H is a single-mode fiber OTDR engineered for precise fault location, attenuation measurement, and loss characterization across extended fiber spans. Operating at 1310 nm, 1550 nm, and 1625 nm, this instrument delivers dynamic ranges of 42 dB, 40 dB, and 39 dB respectively, with measurement cycles between 30 seconds and 3 minutes. Distance accuracy of ±(0.75 m + measurement distance × 2 × 10⁻⁵ + 2 cm) and loss measurement repeatability of ±0.015 dB (typical) support demanding field and laboratory applications.

Yokogawa AQ7286H — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Yokogawa AQ7286H. 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 Yokogawa AQ7286H 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.
