The technology aims to provide early detection of risks that could damage subsea energy and telecommunications infrastructure. The project is based on Distributed Acoustic Sensing (DAS) technology, which uses fiber-optic cables to detect and measure unusual vibrations along the seabed. The Border Guard said the system analyzes changes in light reflections within fiber-optic cables, making it possible to identify activities such as ships dragging anchors near critical infrastructure. The initiative comes amid growing concerns over damage to undersea energy and data cables in the Baltic Sea region, where several incidents have been reported in recent years. While some of the damage has been attributed to natural causes, authorities have raised the possibility of sabotage in other cases.
