The hardware-software complex "Dunay" allows to detect the vibration of the soil (acoustic vibrations) at a distance of several tens of kilometers along the optical cable.

A standard single-mode telecommunication fiber (G. 652) is used as the sensing element.

The application of the system:

  • Monitoring and diagnostics of pipelines:
    • Monitoring of routine maintenance.
    • Monitoring of the protected area.
    • Perimeter security.
  • Monitoring of objects of transport infrastructure:
    • Railroad tracks of the Runway.
    • Bridges, tunnels, highways.
  • Protection of communication lines.
