Advantest Q82227

High Power Input Optical Sensor (Q82227)
Maximum Input Power: +27 dBm
The Q82227 is for long-wavelength, high-sensitivity, and high power light. The sensor is capable of measuring light input up to +27 dBm. Thus, it is suitable for measuring output from optical-fiber amplifiers, the pumping light source of opticalfiber amplifiers, and high-output devices such as LDs for optical CATVs. Also, noise level for Q82227 is |80 dBm, therefore, it can corresponds to measurement where wide dynamic range is necessary.
