Repeatability: ± 0.02 dB
Optical Connector: FC/APC
Supported Fiber: Single-mode (SM) 9/125 µm
Key Features
Fine 0.05 dB attenuation granularity enables precise optical power control and measurement validation across wide dynamic range scenarios.
Exceptional ± 0.02 dB repeatability and ± 0.1 dB linearity ensure consistent, traceable results for production testing and compliance verification.
High optical return loss (≥ 60 dB) minimizes back-reflection artifacts in sensitive measurements.
Low insertion loss (≤ 2.5 dB) preserves signal integrity in cascaded test setups.
Standard FC/APC connectors simplify field deployment and reduce insertion-related uncertainty.
Typical Applications
Optical receiver sensitivity and dynamic range characterization
Transceiver and module power compliance testing
Optical link loss budgeting and validation
Component attenuation measurement and verification
Signal path validation in optical test benches
Compatibility & Integration The AQ8201-31B integrates directly into Ando AQ8201A, AQ8203, AQ8202, and AQ8204 measurement systems as a plug-in module. It operates across the wavelength band from 1200 nm to 1600 nm, accommodating standard single-mode fiber (9/125 µm). Units ship with NIST-traceable calibration certificates and measurement data.

Ando AQ8201-31B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Ando AQ8201-31B. Calibration covers attenuation accuracy at 5 or more set values across the full range (0 to rated maximum dB), attenuation linearity, wavelength-dependent attenuation at 1310 nm, 1490 nm, and 1550 nm, insertion loss at minimum attenuation (0 dB position), and polarization-dependent loss (PDL) where applicable. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Ando AQ8201-31B faults: motor and gear mechanism wear (attenuation steps or loss of smooth control), optical port contamination, EEPROM calibration data corruption. Most common faults are motor or gear mechanism wear on variable attenuators causing attenuation steps or loss of smooth control, optical port contamination reducing dynamic range, and EEPROM calibration data corruption on digitally controlled models.
