The Finnish Border Guard Tests Safeguarding of Subsea Cables Together with Its Partners

Finland Tests Early-Warning System Detecting Threats to Subsea Cables

Finland deploys new system to detect threats to undersea cables — distributed acoustic sensors measure vibrations from the seabed and informs the authorities and operators of suspicious activities

Finnish companies and academic institutions, alongside the Finnish Navy and Border Guards, worked together to develop a system that used existing undersea cables to detect potential disturbances on the seabed. This system would allow the authorities to respond to any detected anomaly, potentially preventing critical undersea infrastructure from getting damaged.
