Power sensor module

The Q82208 is a long-wavelength, high-sensitivity optical sensor/power sensor module from Advantest. Key Features Sensor type: InGaAs (Indium Gallium Arsenide) Wavelength range: 800 to 1700 nm Single channel (1 ch) High sensitivity: achieves –94 dBm by cooling the InGaAs photo-diode Measurement 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 more Low-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 mainframe Compatible with FC, SC, ST, MU and plug-in connectors Suitable for dispersion-shift fibers (core diameter ≤10 μm, NA ≤0.19) Applications Long-wavelength, high-sensitivity optical power measurements Optical fiber testing and characterization Dispersion-shift fiber measurements
