This unit
The Keysight 81566A is a plug-in optical attenuator module for the Lightwave Solution Platform that delivers precise control of optical power levels across the C and L bands. It combines variable attenuation with integrated power control functionality, set a specific output power level directly while automatically compensating for input power fluctuations. This ensures stable output power independent of source variations, making it ideal for demanding photonic test environments.

Compatibility & Integration The 81566A integrates directly into Keysight's Lightwave Solution Platform. Compatible mainframes include the 8163A/B, 8164A/B, and 8166A/B. The module operates as a precision attenuator and power controller within these integrated test systems, providing automated optical power management for multi-instrument measurement workflows.
Agilent / Keysight 81566A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 81566A. 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 Agilent / Keysight 81566A 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.
