Power sensor module

The Q82208 is a long-wavelength, high-sensitivity optical sensor/power sensor module from Advantest.Key FeaturesSensor type: InGaAs (Indium Gallium Arsenide)Wavelength range: 800 to 1700 nmSingle channel (1 ch)High sensitivity: achieves –94 dBm by cooling the InGaAs photo-diodeMeasurement range: 3.9810E-07 μW to 0.01 W (approx. –94 dBm to +10 dBm)High-return-loss design – uses optical fiber with slant-polished ends to suppress reflection, achieving return loss of 50 dB or moreLow-loss, high-return-loss adaptor – provides 45 dB or more return loss with PC polished connectors (typical return loss without adaptor is 14 dB)Measurement accuracy: 5.5%Form factor: Plug-in module for Q8221 power meter mainframeCompatible with FC, SC, ST, MU and plug-in connectorsSuitable for dispersion-shift fibers (core diameter ≤10 μm, NA ≤0.19)ApplicationsLong-wavelength, high-sensitivity optical power measurementsOptical fiber testing and characterizationDispersion-shift fiber measurements
