This unit
The Yokogawa AQ1205A is a compact, handheld Optical Time Domain Reflectometer (OTDR) engineered for field installation, maintenance, and troubleshooting of single-mode fiber networks. Operating at 1310 nm and 1550 nm, this instrument delivers high dynamic range performance suitable for Passive Optical Network (PON) systems with up to 64-port splitter configurations. The AQ1205A combines core OTDR functionality with optional integrated optical power meter and light source modules, enabling multi-parameter fiber characterization without switching between separate instruments.

Yokogawa AQ1205A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Yokogawa AQ1205A. 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 AQ1205A 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.
