Sea and Terrestrial

Fiber optic used to monitor sea
and terrestrial activity and traffic

Monitor and locate in real-time the sea and terrestrial activity near the fiber optic cable such as tidal motion, earthquake, tsunami, mammals, and vessels or vehicles.

Fosina is using the existing subsea and terrestrial fiber optic cables along roads to convert them into real-time and distributed sensors up to 200 km in length.

On land, the solution is provided with a web-based application that can operate the interrogator remotely and generate notifications for congestion detection, traffic monitoring and average speed.  

In the marine environment, the world leading sensitivity of the interrogator enabled Fosina to monitor tidal motion, ship movement and earthquakes using already deployed subsea cables.

Thanks to our expertise in developing customized and leading fiber optic sensing technologies, Fosina developed a DxS that is enabling our clients to monitor multiple types of events using a single DxS interrogator connected to a single fiber end and at longer fiber range compared to existing, single-measurement technologies in the market.

The environmental qualification and smaller footprint of the DxS allow our clients to deploy this technology globally, sustainably, and reliably.
