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.
main feature:
-
Guaranteed ±2.5% measurement accuracy under reference conditions
-
The wide wavelength range and dynamic range cover a wide band from 400 to 1870nm, and provide a dynamic range of 100dB or more for loss measurement. (It depends on the sensor.)
-
The AQ2733 and AQ2734 sensor units achieve a polarization dependence of 0.02dBp-p or less.
-
The AQ2734 sensor unit uses a photodiode with a flat wavelength sensitivity of 1300 to 1800nm to achieve accurate measurement at 1650nm.
-
The LD unit has an internal isolator, which can keep the optical output level stable at ±0.003dB. The optical power attenuation function can reduce the optical power to 6.0dB in 0.1dB steps.
-
Support a variety of connectors and a variety of optical connectors only need to replace the universal and connector adapter (except AQ4214).
-
The optical power can be reduced to 6.0dB in steps of 0.1dB.
-
Since the internal self-reflection data is stored in the memory by a single unit for correct operation, even high reflectance attenuation can be measured with excellent accuracy.
-
The internal high stability sensor can be used with the LD unit to provide stable reflection attenuation measurement.
-
Equipped with a return loss unit and an LD unit, the display will show the attenuation of the reflectivity after measuring the reference reflectivity, just disconnect the optical cable under test.
