Distributed Fiber Optic Sensing (DFOS): Industry Applications & Solutions

Distributed Fiber Optic Sensing technology provides real-time, continuous monitoring over long distances, offering revolutionary solutions across various critical industries. By turning a standard fiber optic cable into a network of thousands of sensors, we can precisely detect changes in temperature, strain, and vibration, ensuring safety, efficiency, and asset integrity.

Energy & Power

High-Voltage Cable Temperature Monitoring

Enable real-time temperature monitoring for power transmission cables and underground cable trenches. Proactively prevent overheating failures caused by overloading or aging joints to ensure the stability and safety of the power grid.

Oil & Gas Pipeline Monitoring

Monitor the temperature, strain, and third-party intrusion events (such as excavation and squeezing) along oil and gas pipelines. Swiftly detect leaks or pipeline deformations to prevent safety incidents and environmental damage.

Nuclear Power Plant Safety Monitoring

Implement crucial temperature and strain monitoring around nuclear reactors and for spent fuel pools. This ensures the operational safety of nuclear facilities by providing critical, real-time data from sensitive areas.

Civil Engineering & Infrastructure

Bridge & Tunnel Structural Health Monitoring (SHM)

By embedding fiber optic sensors within main bridge girders and tunnel linings, continuously monitor structural strain, vibration, and temperature changes. Assess fatigue damage and crack development to provide early warnings for structural issues.

Dam & Slope Stability Monitoring

Achieve real-time monitoring of displacement, strain, and seepage within dam structures and on slopes. This proactive approach helps prevent geological disasters such as landslides and collapses.

Building Structural Monitoring

Conduct long-term health monitoring for the steel or concrete structures of high-rise buildings and large-span industrial plants, guaranteeing architectural safety and longevity.

Security & Perimeter Defense

Perimeter Intrusion Detection

Deploy fiber optic cables along the perimeters of airports, military bases, oil fields, and high-speed railways. The system detects vibrations caused by climbing, cutting, or approaching vehicles, providing real-time location and alarms for any intrusion attempt.

Pipeline Theft & Vandalism Prevention

Monitor oil, gas, and water pipelines for abnormal vibrations associated with activities like illegal tapping, drilling, or excavation. This allows for immediate intervention to prevent theft and sabotage.

Geological & Environmental Monitoring

Geohazard Early Warning Systems

Install fiber optic cables in landslide-prone zones and fault areas to monitor soil displacement and strain variations. This provides crucial advance warning for impending landslides, mudflows, and other geological hazards.

Permafrost & Glacier Monitoring

Analyze freeze-thaw cycles in permafrost regions through distributed temperature sensing, providing vital data for the stability of engineering projects like the Qinghai-Tibet Railway. Monitor glacier movement to study the impacts of climate change.

Marine & Offshore Engineering

Utilize DFOS for strain and temperature monitoring of subsea cables and offshore platforms. It is also highly effective for leak detection in underwater pipelines, safeguarding marine assets.

Industrial & Manufacturing

Chemical Tank & Pipeline Monitoring

Perform real-time monitoring of temperature and pressure variations in chemical storage tanks, as well as corrosion and leakage along pipelines. This helps prevent hazardous chemical spills and related safety accidents.

Mine Safety Monitoring

Embed fiber optic sensors in mine tunnels and pillars to monitor rock mass strain and displacement. This provides early warnings for potential roof collapses, rock bursts, and other mining accidents, enhancing worker safety.

Data Center & IT Room Monitoring

Deploy distributed temperature sensors across server racks and cooling ducts. This allows for the optimization of cooling systems, prevents equipment from overheating, and ensures the stable operation of critical IT infrastructure.
