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.

Optical power referenced to 1 millimatt

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
