Compatibility & Integration The AQ5521 integrates with complementary optical test modules including Visual Fault Locators (VFL) for break pinpointing, Optical Light Source (OLS) functions, and Optical Power Meter (OPM) capabilities. USB connectivity enables data transfer and remote operation support. The instrument supports field and laboratory workflows with portable operation capability.
Ando AQ5521 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Ando AQ5521. 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 Ando AQ5521 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.
