An optical spectrum analyzer is a measuring instrument that analyzes the optical wavelength components of optical devices such as semiconductor lasers and fiber lasers in order to evaluate wavelength characteristics. The AQ6380 will contribute to the research and development of devices and systems to meet the growing demand for high-capacity, high-speed optical communication networks.
Development Background
Wavelength division multiplexing (WDM) technology is now widely used throughout high-capacity, high-speed optical communications networks, from backbones to access points, to meet the growing demand for such networks that is being driven by the expansion of communication services such as IoT, cloud computing, and 5G. In order to evaluate the characteristics and quality of the optical devices and optical components used in these networks, high-performance measuring instruments are essential. In particular, next-generation optical transceivers and dense wavelength division multiplexing (DWDM) technology require even higher resolution and wider dynamic range.
The newly developed AQ6380 is a highly reliable optical spectrum analyzer that offers the performance to efficiently and effectively measure devices and systems used in the most demanding photonics applications. The product is based on the dispersion spectroscopy optical design technology and extensive experience in the optical measurement industry that
Features
1. Dispersion spectroscopy supporting a wide variety of applications
Dispersion spectroscopy can cover a wide range of wavelengths and has features that can be applied to measurements of laser light and broadband light, and as such the AQ6380 can be used to evaluate the performance of laser light sources, broadband light sources, optical passive components, and other optical components and devices used in a wide variety of applications.
2. Industry-leading wavelength resolution and accuracy
At
3. High noise suppression ratio
The AQ6380 has outstanding performance in suppressing noise caused by input light and achieves a noise suppression ratio of 80 dB. It offers rapid, high-dynamic-range laser side-mode measurement and other such measurements of optical spectra with level differences. This puts the AQ6380 in the top performance class in the industry for dispersion spectroscopy optical spectrum analyzers*2.
4. Rapid measurement
A new "RAPID" sensitivity mode that is specialized for continuous wave light measurement measures light spectra up to 20 times faster than the AQ6370D model under typical measurement conditions.
5. Improved operability and ease of use
A large touchscreen with multi-touch support further improves intuitive operability. This enables users to perform actions such as changing measurement settings, performing measurements and analysis, and changing the optical spectrum view as if using a tablet. Furthermore, a test application that navigates the user through a series of operations from setting measurement conditions to outputting analysis results specific to the measurement subject is also available. This enables users to use the AQ6380 without having to be concerned with a wide range of settings.
6. Capable of measuring original optical spectrum
The AQ6380 is equipped with a function that suppresses the absorption of light of a specific wavelength by removing the minute amount of water vapor from the air inside the monochromator. This enables measurement of the original optical spectrum of the light being measured.
