FBG Wavelength Interrogator

The FBG Wavelength Interrogator AGSWA is designed to be a robust, reliable and long-term filed operation for the FBG sensing system. Based on a built-in wavelength analysis module, AGSWA can update the data in high accuracy and high frequency.


AGSWA responds directly to the user commands of the optical interrogator core and outputs sensor wavelength data. It provides a single suite of tools for data acquisition, computation, and analysis of optical sensor networks.
