81635A Keysight Dual Optical Power Sensor

• Polarization correlation: <±0.015 dB

• Power uncertainty: ±3%

• Power range: +10 to -80 dBm

• Wavelength range: 800 nm to 1650 nm

• Dual InGaAs detectors have low noise and wavelength dependence

The Keysight 81635A dual optical power sensor is ideal for accurate power measurements on fiber optic devices. This modular dual-way sensor is suitable for use with a variety of Keysight 816x optical waveform hosts and can be used individually or in multiple combinations to measure multi-channel devices in parallel. Output fibers can be easily connected using a flexible connector adapter or bare fiber adapter from Yestech.

This module can run a variety of measurement applications, such as data logging, stability testing, and recording minimum and maximum values at different times. The trigger synchronization capability with the tunable laser source module allows you to perform powerful spectral measurements - with higher resolution and better polarization correlation - enabling cost-effective and time-saving multi-channel expansion. The module can record up to 20,000 samples with an average time of up to 100 µs.

Functional features.

A comprehensive sampling and triggering concept (hardware trigger lines, filtering, event triggering, hardware timers, analog outputs) is used, allowing easy integration into various control schemes.

The module is suitable for all communication bands and accepts standard singlemode and multimode fibers with core sizes up to 62.5 µm.
