This unit
The Yokogawa AQ7283A is a dual-wavelength Optical Time Domain Reflectometer engineered for fault location, loss analysis, and fiber length measurement in single-mode optical networks. Operating at 1310 nm and 1550 nm, this modular OTDR delivers dynamic range of 42 dB and 40 dB respectively, with measurement capability to 512 km. The instrument features an 8.4-inch color TFT display, multi-touch capacitive interface, and selectable pulse widths from 3 ns to 10,000 ns, enabling precise characterization of installed fiber infrastructure.
Field-deployable with up to 15 hours battery life and internal/external data storage via USB and SD card, the AQ7283A integrates into the AQ7280 platform for customizable test configurations.

Yokogawa AQ7283A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Yokogawa AQ7283A. 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 AQ7283A 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.
