  • Monitoring roads, bridges, tunnels, railways, pipelines and others


Advantages of Our Advanced Distributed Fiber Optic Sensors

  • Embrace the forefront of innovation with our industry-leading DFOS technology.
  • Take advantage of our cost-effective sensor pricing.
  • Benefit from straightforward and swift setup procedures.
  • Count on robust resistance to both physical and chemical wear.
  • Enjoy peace of mind with our sensors' immunity to electromagnetic disturbances.
  • Access unparalleled measurement distances.
  • Ensure seamless integration with the infrastructure you're monitoring.
  • Depend on our sensors for consistent reliability and pinpoint accuracy.
  • Employ sensors versatile enough to support any DFOS measurement approach, including Rayleigh, Brillouin, and Raman scattering techniques.

Fit and Strong

Experience excellent representation of the monitored phenomena, thanks to adequate stiffness and ribbed surface.

They can even replace steel rebars and cover very long distances.

Monolithic structure

Our sensors provide readings that perfectly reflect the observed phenomena.

There are no intermediate layers separating the fibers from the structure.

Unique Shape

Our unique sensor's shape ensures perfect integration between the sensor and the surrounding structure.

These sensors provide the highest quality of information.

3D measurements

Achieve accurate measurements ensured by direct displacement (shape) measurement by the 3D Sensor.

Choose from different sensor dimensions to match your project requirements.
