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.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
