This unit
The Agilent/Keysight 81624C Optical Power Head delivers accurate optical power measurements across the near-infrared spectrum using an InGaAs detector. Operating with the Keysight N7749C Optical Head Interface, this module enables flexible remote power head placement and supports both guided and free-space optical configurations. The 5 mm detector accommodates standard single-mode and multimode fibers (up to 100 μm core, NA ≤ 0.3), parallel beams to 4 mm diameter, and bare fibers via a selection of magnetic D-shaped adapters that enable rapid changeover without fiber disturbance.
Technical Specifications
- Sensor: InGaAs, 5 mm diameter
- Wavelength Range: 800 nm to 1700 nm (specification accuracy: 1000 nm to 1630 nm)
- Power Range: −90 dBm to +10 dBm
- Measurement Accuracy: ± 2.2% (1000 nm to 1630 nm)
- Polarization Dependence: < ± 0.01 dB (typical < ± 0.002 dB)
- Spectral Ripple Uncertainty: < ± 0.006 dB (typical 60 dB typical
- Averaging Time: 100 µs to 10 s (controllable)
Key Features
- Broad spectral coverage from 800 nm to 1700 nm for telecommunications and research applications
- Support for multimode fibers to 100 μm core diameter with low numerical aperture (≤ 0.3)
- Accepts open beams and bare fibers through field-replaceable adapter system
- Low polarization dependence ensures reliable measurement across polarization states
- Auto-ranging capability with selectable measurement modes (linear or logarithmic)
- Magnetic D-shaped adapters prevent fiber twisting during adapter changes
Typical Applications
- Optical power measurements in fiber-optic test systems
- Wavelength-dependent power characterization from 800 nm to 1700 nm
- Multi-fiber and free-space optical system validation
- Telecommunications and photonics laboratory testing
Compatibility & Integration Designed specifically for the Keysight N7749C Optical Head Interface. Compatible with mainframes supporting the N7749C bus architecture. The 8162-C series heads are not backward-compatible with earlier 81618A/81619A interfaces.

Agilent / Keysight 81624C — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 81624C. 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 81624C 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.
