Optical power sensor module

Key Features of the Agilent 81634A High-Performance Optical Power Sensor: Equipped with a thermally stabilized (cooled) and hermetically sealed InGaAs detector, ensuring stable and reliable measurements independent of ambient environmental influences like humidity, dust, and temperature. Wide Wavelength & Power Range: Covers a wavelength range of 800 nm to 1700 nm and a power measurement range from +10 dBm to -110 dBm. Low Polarization Dependence & High Linearity: Features low polarization dependence of <±0.005 dB and high linearity (CW +10 dBm to -70 dBm) of <±0.015 dB ±2 pW, making it specially designed for spectral ripple and low PDL measurements of optical components. Modular & Flexible Design: The module fits into all Agilent 816x Lightwave mainframes (e.g., 8163A, 8164A, 8166A) and can be used singly or in multiples for parallel measurements of multichannel devices. Versatile Measurement Applications: Capable of running multiple measurement applications such as data logging, stability testing, and recording minimum and maximum values over time. High-Speed Data Logging: Can log up to 20,000 samples with an averaging time as low as 100 µs. Advanced Triggering & Synchronization: Features a comprehensive sampling and triggering concept (including hardware trigger lines, filtering, event trigger, hardware timer, analog output). Triggered synchronization with tunable laser modules enables powerful spectral measurements with higher resolution and better polarization dependence. Traceable Calibration: Traceable to NIST (National Institute of Standards and Technology) and PTB (Physikalisch-Technische Bundesanstalt), ensuring measurements are referenced to internationally accepted standards. Easy Fiber Attachment: The output fiber is easily attached using Agilent's flexible connector adapters or a bare-fiber adapter.
