The ST-SEWS system is an advanced submarine optical cable monitoring and early warning solution designed to enhance the safety, survivability, and operational efficiency of undersea communication infrastructure. It utilises cutting-edge distributed optical fibre sensing technology to enable real-time hazard detection, early warning, and event localisation, preventing costly damage to submarine optical cables.
Most existing fibre optic sensing systems use Φ-OTDR technology, which is limited to short distances (30-50 km) and primarily used for land-based perimeter security.
ST-SEWS is the first commercial solution to provide real-time, long-distance monitoring of submarine optical cables, covering up to 1000 km with repeaters.
