This unit
The Agilent/Keysight 81633A is an optical power sensor module for precision measurements in lightwave communication systems. Built around an InGaAs detector with a 5 mm diameter active area, it delivers accurate power readings across the 800 nm to 1700 nm spectrum. The module integrates into Agilent/Keysight Lightwave Mainframes - including the 8163A/B Multimeter, 8164A/B Measurement System, and 8166A/B Multichannel System - via an external interface module (81618A or 81619A).
Operation requires SCPI programming and compatible optical connector adapters, sold separately.
Technical Specifications
- Sensor Type: InGaAs
- Detector Area: 5 mm diameter
- Wavelength Range: 800 nm to 1700 nm
- Power Range: +10 dBm to −90 dBm
- Absolute Accuracy: < ±2.5% (1000 nm to 1630 nm)
- CW Linearity: < ±0.015 dB ±2 pW (+10 dBm to −70 dBm)
- Polarization-Dependent Loss Uncertainty: ±0.015 dB (typical)
- Spectral Ripple Uncertainty: ±0.015 dB (typical)
- Operating Temperature: 0 to 40°C, non-condensating
Key Features
- High-speed data logging up to 20,000 internally or externally triggered values
- Real-time measurement capability: 50,000 readings per second (system-dependent)
- SCPI standard programming interface
- Low polarization-dependent loss and spectral ripple characteristics
- Flexible optical connector options via separate 81000xI series adapters (FC, SC, LC, MU, bare fiber, open beam)
Typical Applications
- Optical power measurements in communication system validation
- Spectral ripple characterization of optical components
- PDL measurement and analysis
- Long-wavelength lightwave system testing across the 800–1700 nm band
Compatibility & Integration The 81633A requires a single (81618A) or dual (81619A) interface module for operation within supported Lightwave Mainframes. SCPI command syntax aligns with the 8164A, 8166A, and 8153A systems, enabling straightforward integration into existing measurement platforms.

Agilent / Keysight 81633A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 81633A. Calibration covers detector responsivity across all specified wavelengths (typically 800-1700 nm range), absolute power accuracy, and EEPROM calibration coefficient update. Compatible with Agilent/HP 8163A/B, 8164A/B, and 8166A/B mainframes.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 81633A faults: FC/PC connector damage, EEPROM failure (mainframe shows unrecognized sensor), reduced responsivity. Common faults include FC/PC input connector damage, EEPROM failure causing the module to appear unrecognized by the mainframe, and reduced detector responsivity from contamination.
