Tokyo, Japan - November 19, 2012
Yokogawa Meters & Instruments Corporation announces that it will release the AQ6150 and AQ6151 optical wavelength meters on November 20. These meters are among the fastest instruments of this type and are capable of simultaneously measuring up to 1,024 wavelengths, for unrivaled measurement efficiency.
AQ6150 standard model and AQ6151 high-accuracy model
The rapid increase in the use of the Internet, smartphones, terrestrial digital broadcasting, and other communications services and devices requires the transmission of vast volumes of data at ever increasing speeds. This is leading to accelerated expansion of core networks (backbone) and metro networks (local area) as well as the construction of data centers. In line with these trends, production of optical transmission systems and the various optical devices that make up these systems is being ramped up, and this is spurring market demand for precise yet efficient optical wavelength test instruments. In addition, fixed wavelength optical sources are being replaced by tunable optical sources as they become more compact and affordable. Therefore, precise optical wavelength meters are required that can accurately measure signals of various wavelengths.
With their capability to simultaneously measure up to 1,024 wavelengths with best-in-class speed and accuracy, the newly developed AQ6150 and AQ6151 optical wavelength meters provide the high performance and measurement efficiency that the market requires.
|Wavelength range||1270 to 1650 nm|

*1 A fiber-optic transmission technology that multiplexes light signals having different wavelengths on a single optical fiber
*2 An optical source that emits light of very stable optical wavelengths and is used as a reference when optical wavelength meters measure other wavelengths. Depending on the usage conditions, such devices must normally be replaced every few years.
*3 A semiconductor laser with a long coherence length that is thus suitable for long-distance transmissions
