Elisa, the Finnish Border Guard and the Finnish Navy successfully tested the securing of submarine cables
The observation equipment connected to Elisa's submarine cable is used to monitor the submarine cable and detect threats to it. The functionality of the system has now been tested by simulating various scenarios, such as dragging an anchor.The detection equipment installed by Elisa enables the acoustic monitoring of submarine cables in the Gulf of Finland, supporting a broader monitoring of seabed safety. The project is based on Distributed Acoustic Sensing, i.e. DAS technology, in which Elisa's submarine cable acts as a sensor that measures exceptional vibrations on the seabed. The DAS
