High Power Optical Sensor The Agilent (now Keysight) 81630B is a High Power Optical Sensor (modul). Agilent (now Keysight) optical power sensors offers accurate power measurements on fiberoptic devices. The modular sensors fit into all 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 100 µs. High power range: +28 dBm Low power uncertainty: +/- 3.0 % Low polarization dependence: < +/- 0.01 dB Spectral ripple: < +/- 0.005 dB Traceable to NIST and PTB Low uncertainty in Power and PDL The traceability gives you the certainty of measurements referenced to internationally accepted standards Comprehensive sampling and triggering concept: hardware trigger lines, filtering, event trigger, hardware timer, and analog output Analog output enables building power control and feedback loops
