Energy Industry

Underground Utility Tunnel

Urban comprehensive pipelines, including communication, electricity, water supply, drainage, heating, and gas pipelines, are critical infrastructures for future smart city development. With the extensive development of smart cities, these pipelines span millions of kilometers, serving as the lifelines of cities. Utilizing advanced fiber optic sensing technology and integrating various Internet of Things (IoT) sensor technologies within comprehensive utility tunnels enables comprehensive intelligent sensing of underground utility tunnel operations.

Critical Site Perimeter Security Monitoring

Distributed optical fiber acoustic sensing technology (DAS) has been widely used in the field of perimeter security. Taking the airport as an example, in the airport perimeter security, the application of DAS system greatly improves the intelligence and automation level of security protection.

Power / Communication Cable Monitoring

This application includes the monitoring of both underground and overhead power cables. In overhead cable monitoring, wind-induced motion monitoring (known as Aeolian vibration monitoring) is crucial. Underground cable monitoring primarily focuses on external damage monitoring and warning, temperature monitoring, and partial discharge monitoring.

Marine Scientific Exploration

Due to the unique marine environment, recent domestic and international experimental studies have demonstrated the distinct advantages and irreplaceability of DAS technology in marine scientific exploration, showcasing a wide range of applications. These include tidal and current monitoring, tsunami and storm detection, marine animal target monitoring, submarine geological imaging, and seabed carbon capture and storage (CCS). The ixDAS-3000 series products, capable of measuring extremely low-frequency signals (detecting signals below 0.01 Hz), fully meet the various application requirements of marine scientific exploration.

Seismic Monitoring

Marine seismic observation has long relied on seabed seismometers, which have high deployment and maintenance costs, resulting in less extensive and dense coverage compared to terrestrial observations. Utilizing long-distance DAS technology and the existing extensive network of submarine optical cables, including retired submarine communication cables or unused “dark” fibers in active cables, a wide-area marine seismic observation network with high spatial sampling densities can be established.
