The Keysight 81634B optical power sensor is the right choice for accurate power measurements on fiberoptic devices. The modular sensor fits into all Keysight 816x Lightwave mainframes and can be used singly or in multiples for parallel measurements of multichannel devices. The input fiber is easily attached using Keysight'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.
