OPTICAL COMMUNICATIONS & NETWORKS

As Yokogawa looked to expand opportunities for test and measurement offerings, we employed the foresight to focus on optical communication networks. This foresight lead to the partnership and eventual acquisition of Ando Electric. This strategic combination leveraged Ando’s in depth optical testing experience since 1980 and Yokogawa’s corporate focus on measurement instruments since 1915 to provide the optical networking industry with a stable supplier even during difficult times in the market space. Yokogawa's strategic partnership with (formerly) ANDO provided precision spectral instrumentation, which is crucial to CWDM and DWDM deployment. Since Ando was embedded in the initial explosion of optical demand, our Optical Spectrum Analyzers helped fuel rapid development of data intense capabilities. Today, we look to the future and continue to innovate with instruments such as the AQ6370 line of OSAs, the AQ6150 series optical wavelength meters and a unique multi-tasking OTDR, which allows testing the health of up to 4 fibers simultaneously.

AQ6150 Series Optical Wavelength Meter

AQ6150 Series Optical Wavelength Meter

The AQ6150 Series Optical Wavelength Meter is designed to accurately measure the optical wavelength of optical devices and systems used in telecommunication applications from 1270 to 1650 nm (including C&L Band). By employing a Michelson interferometer and a high speed Fast Fourier Transform (FFT) algorithm, the AQ6150 series can measure single wavelength laser signal, as well a multiple wavelength laser signal from a DWDM system and Fabry-Perot laser. Furthermore, this technology enables the measurement of modulated laser signals in addition to the CW signal from an optical transceiver. The optimized optical design and data processing routine significantly reduces the measurement time and improves manufacturing throughout.
