State-of-the-art basic FBG interrogator for strain sensing

Technobis is proud to present the Gator series, the World’s First ASPIC based FBG interrogator modules.

Technobis Fibre Technologies has developed the Next Generation Fibre Bragg Grating (FBG) metrology system Gator is based on Integrated Photonics technology. The Gator features specifically designed integrated photonics functionality (patented technology) that forms the basis for all Gator series with the standard specifications as mentioned.
Based on the Gator platform different variations and chipsets are available for different measurement capabilities and application requirements. In addition a multiplexing feature is available in combination with these different measurement capabilities.
