The Ando AQ2743 Optical Power Sensor when used with OPM Unit and powermeter mainframe is used to measure power from large-diameter fiber emission, free-space beam. Photoreceptor: Cooled Ge 5 mm. Wavelength: 750 to 1800 nm. Power level range CW light: -80 to +10 dBm, 10 pW to 10 mW. Power level range 270 Hz chopped light: -90 to +7 dBm, 1 pW to 5 mW. Polarization dependence conditions (Wavelength 1550nm, SM fiber): 0.03 dB p-p typical. Accuracy under reference conditions (Power level -20dBm (10 uW), CW light): ±2.5% (at 1310nm calibration point). Total accuracy (Power level -20dBm (10 uW), CW light): ±5% (950 to 1600 nm). Linearity for one wavelength within wavelength specified in total measurement accuracy (constant temperature 23 ±5°C): ±0.05 dB (950 to 1600nm, -50 to +10 dBm). Noise, Averaging 1 s (measurement interval 100 ms averaging executed 10 times): CW light -73dBm or less, Chopped light -83d8m or less. Analog out: 0 to approx. +2V for each range, output impedance 1.5 k-ohms or less.
