Elisa Tests DAS on Subsea Cables, Simulating Anchor-Drag Threats
3 articles · Updated · Telecompaper EN · Jun 5
Summary
Elisa said it successfully tested distributed acoustic sensing on its submarine cable network to spot threats and protect the infrastructure from damage or interference.
Observation equipment was connected directly to an Elisa cable, allowing the system to monitor activity around the line and detect potential risks.
The trial was carried out with Finland's Border Guard and Navy, and included simulated incidents such as an anchor being dragged across the seabed.
The test points to closer use of sensing technology and security agencies to guard critical subsea communications links.
