Used Keysight / Agilent 81636B Fast Optical Power Sensor, 1250 to 1640nm, 25micorS Average time

Product Highlights

Keysight's 81636B general purpose 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 output 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 100,000 samples with averaging time as low as 25µs. The analog bandwidth of 17kHz supports fast logging without distortion and the analog output is available for real-time oscilloscope measurements.

• 25 µs minimum averaging time and 17 kHz analog bandwidth
• Dynamic range > 55dB in manual range mode
• Power uncertainty of ±3%
• Low polarization dependence of <±0.015dB
• 100,000 measurement samples
