Product Description:
In today's multimedia age, a variety of new services are emerging. Multimedia communication requires an optical access network to handle the large-capacity information transmission required by the society, and is currently under construction. At the same time, the emergence of fiber amplifiers has triggered a sharp rise in the demand for various optical devices. In this context, the AQ2140 optical multimeter was developed as a basic optical measuring instrument, suitable for a wide range of applications from R&D to optical fiber and component manufacturing, as well as construction and maintenance. The stand-alone machine provides high-precision, powerful functions and high-speed measurement, so that it can be used as an optical power meter, stabilized light source, loss tester or return loss measuring instrument.
feature:
-
Measurement accuracy of ±2.5% is guaranteed under the reference conditions
-
Covers a wide waveband from 400 to 1870nm, and provides a dynamic range of 100dB or more for loss measurement (It depends on sensors)
-
The AQ2733 and AQ2734 sensor units achieve a low polarization dependence of 0.02dBp-p or less
-
The AQ2734 sensor unit uses a photodiode with flat wavelength sensitivity from 1300 to 1800nm, for accurate measurement at 1650nm as well
-
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
-
The internal high-stability sensor can be used together with the LD unit to provide stable reflectance attenuation measurement
-
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
-
A wide variety of optical connectors can be used just by exchanging the universal connector adapters (AQ4214 excluded)
-
Optical power can be decreased in 0.1 dB steps to 6.0dB
-
The LD unit has an internal isolator that maintains optical output level stability at ±0.003dB
