HP-Agilent/Keysight 81635A

Agilent’s 81635A dual optical power sensor is the right choice for accurate power measurements on fiberoptic devices. The modular dual sensor fits into all Agilent 816x Lightwave mainframes and can be used singly or in multiples for parallel measurements of multichannel devices. The output fiber is easily attached using Agilent’s flexible connector adapters or bare-fiber adapter. The module can run measurement applications like data logging, stability and recording minimum and maximum values over time. Triggered synchronization with tunable laser modules enables powerful spectral measurements, with the advantages of higher resolution, better polarization dependence and cost-and-time-efficient multichannel expandability. The module logs up to 20,000 samples with averaging time as low as 100µs. – Polarization dependence of <±0.015 dB - Power uncertainty of ±3% - Standard SM and MM up to 62.5 µm core size - InGaAs detectors for low noise and low wavelength dependence - Power range from +10 to -80dBm - Comprehensive sampling and triggering concept (hardware trigger lines, filtering, event trigger, hardware timer, analog output)
