ANDO AQ2743 Optical Power Sensor

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.

*This is a Web introductory price for one calibration of the ANDO AQ2743. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Related Optical Terms and Definitions. For a complete list go to our  Terms and Definitions Page.

A change in the optical frequency caused by direct modulation of the laser. A chirp is a signal in which the frequency increases ('up-chirp') or decreases ('down-chirp') with time. In some sources, the term chirp is used interchangeably with sweep signal.

The extent to which optical power from one signal path is prevented from reaching another signal path.

Polarization Extinction Ratio
Polarization Extinction Ratio is the ratio of optical power in the slow axis of the polarization maintaining fiber to optical power in the fast axis within a specified wavelength range.

Sidemode Suppression Ratio
Sidemode Suppression Ratio is the ratio of average signal power to the optical power of the highest sidemode within a distance from 0.1 to 6 GHz to the signal’s optical frequency, expressed in dB.

Wavelength Stability
Wavelength Stability is the change of wavelength during given time span, expressed as ± half the span between the maximum and the minimum of all actual wavelengths.
