Maria Ebbinghaus works as Marketing Manager at FBGS.

In view of the growing number of Distributed Acoustic Sensing (DAS) applications FBGS is proud to announce the launch of a special designed vibration sensitive All Grating Fiber for long-range Distributed Acoustic Sensing (DAS) systems.

The soundAGF® is engineered to increase the back reflected light in the fiber within a certain wavelength range, enabling a better Signal to Noise Ratio (SNR) and therefore a better measurement quality.

The fiber bragg gratings are inscribed with our cost-effective DTG® technology during the drawing of the long range low loss optical fiber before the primary coating is applied.

The enhanced back reflection characteristics can be tailored to the customer’s needs with respect to center wavelength, bandwidth and reflectivity. Due to our exclusive Ormocer® coating the fiber can be used in a wide operating temperature range from -200°C up to 200°C.

The soundAGF® is intended for the use with all available Distributed Acoustic Sensing (DAS) systems to enhance the systems performance and sensitivity to improve: Possible applications are:

  • Pipeline monitoring (leak detection, corrosion detection, external events)
  • In-well low and high temperature monitoring
  • Railway monitoring (track and train)
  • Perimeter security sensing
  • Subsea & highway monitoring
  • Industrial plant monitoring
  • Smart city applications
