Ando AQ2140 Optical Multimeter
The Ando AQ2140 Optical Multimeter was developed to serve as universal optical testing instrument. It can be used for a wide range of applications from R&D-- to optical fiber and component manufacture, as well as construction and maintenance. This modular system provides high precision, powerful functions and high-speed measurement, making it one of the most popular instruments for general and integrated applications.
Features
Sensor Unit
High Accuracy
Measurement accuracy of ±2.5% is guaranteed under the reference conditions.
Wide wavelength range and dynamic range
Covers a wide waveband from 400 to 1870nm, and provides a dynamic range of 100dB or more for loss measurement.
(It depends on sensors.)
Low polarization dependence
The AQ2733 and AQ2734 sensor units achieve a low polarization dependence of 0.02dBp-p or less.
Support for the 1650nm band
The AQ2734 sensor unit uses a photodiode with flat wavelength sensitivity from 1300 to 1800nm, for accurate measurement at 1650nm as well.
Light source unit
High stability
The LD unit has an internal isolator that maintains optical output level stability
at ±0.003dB.
Optical power attenuation function
Optical power can be decreased in 0.1 dB steps to 6.0dB.
Support for a variety of connectors
A wide variety of optical connectors can be used just by exchanging the universal connector adapters (AQ4214 excluded).
Return Loss unit
High accuracy
Because internal self-reflectance data is stored by individual units in memory to correct operations, even high-reflectance attenuation can be measured with excellent accuracy.
High stability
The internal high-stability sensor can be used together with the LD unit to provide stable reflectance attenuation measurement.
Simple operation
Mounted with a return loss unit and an LD unit, the display will show reflectance attenuation after measurement of reference reflectance by merely connecting the measured fiber cable.
