Yokogawa AQ6370E Optical Spectrum Analyzer

Yokogawa announces the AQ6370E optical spectrum analyzer

  • The AQ6370E optical spectrum analyzer is an enhanced version of Yokogawa Test & Measurement’s AQ6370D model.
  • Covering a wavelength range from 600 nm to 1700 nm, this analyzer is suitable for telecom test applications.
  • Equipped with an LCD touchscreen, it enables single-mode DWDM-class fibers and multimode VCSE-sourced fibers to be tested with a single instrument.

Equally suitable for industry, universities and research institutions, the AQ6370E can be used to characterize a wide range of components, including lasers for optical communications, optical transceivers, and optical amplifiers.

The Yokogawa AQ6370E optical spectrum analyzer is designed to meet the growing need for highly precise and easy to use test equipment in the R&D and production of optical communications devices and equipment. This is driven in part by the growth in the use of cloud services, 5G communications, and other information and communication services that require large-capacity and high-speed optical communication networks. This trend is driving the development of next-generation optical devices and components that support large-capacity optical communication networks. Evaluating the characteristics and quality of these devices and components requires high-precision optical test instruments that are able to analyze the light wavelength components and measure the wavelength characteristics.

The new AQ6370E is an evolution of the AQ6370D optical spectrum analyzer launched by Yokogawa in 2014. It boasts several new functions and features aimed at simplifying development and production processes.

One of these new features is HCDR (high close-in dynamic range) mode, with which a user can measure a single longitudinal mode laser with a high close-in dynamic range. Close-in dynamic range is a key performance criterion when developing lasers and optical devices.

There is also a SMSR (side mode suppression ratio) mode, which can reduce SMSR measurement time, and an APP mode. APP mode provides a device under test (DUT) specific user interface that navigates the user from configuration settings to test result output, so that even customers who are unfamiliar with optical spectrum analyzers can use it easily.
