Roads & Highways

Monitor traffic patterns, detect pavement degradation, and identify subsidence risks across your road network. DFOS transforms existing fiber alongside highways into a continuous sensing system.

  • Traffic Flow Analysis: Vehicle counting, speed estimation, and congestion detection using acoustic signatures
  • Pavement Condition: Detect developing cracks, potholes, and surface deterioration before they become hazards
  • Subsidence Detection: Early warning of ground movement, sinkholes, and undermining beneath roadways
  • Weather Impact: Monitor freeze-thaw cycles and thermal stress on pavement structures
Resolution: 1m
Coverage: 50km/unit
Update rate: Real-time

Pipelines

Protect oil, gas, and water pipelines with continuous monitoring for leaks, intrusion, and structural integrity. DFOS provides the sensitivity and coverage that point sensors cannot match.

  • Leak Detection: Identify leaks as small as 0.1% of flow rate through temperature and acoustic anomalies
  • Third-Party Interference: Detect excavation, drilling, and unauthorized activity near pipeline rights-of-way
  • Integrity Monitoring: Track strain accumulation, ground movement, and structural stress over time
  • Flow Profiling: Monitor flow characteristics and detect anomalies indicating blockages or product changes
Leak sensitivity: 0.1%
Location accuracy: ±5m
Detection time: <60s

Buildings

Monitor building structural health continuously, from foundation settlement to seismic response. Embed fiber during construction or retrofit existing structures for comprehensive monitoring.

  • Structural Health: Monitor beam deflection, column strain, and connection stress in real-time
  • Seismic Response: Record building response during earthquakes with high temporal resolution
  • Foundation Monitoring: Detect differential settlement and foundation movement early
  • Load Tracking: Understand occupancy patterns and live load distribution across floors
Strain resolution: 0.1με
Sampling rate: 10kHz
Coverage: Full structure

Bridges

Comprehensive bridge monitoring covering deck strain, cable tension, pier settlement, and traffic loading. Identify structural issues before they become safety concerns.

  • Strain Monitoring: Continuous measurement of deck and girder strain under varying loads
  • Cable Tension: Monitor stay cables and suspension cables for tension changes and fatigue
  • Load Assessment: Weigh-in-motion capability for traffic load characterization
  • Early Warning: Automated alerts when measurements exceed defined thresholds
Deflection accuracy: ±0.5mm
Load estimation: ±5%
Monitoring: 24/7

Tunnels

Monitor tunnel structural integrity, ground movement, and water ingress in real-time. DFOS provides complete coverage of tunnel linings with a single sensing cable.

  • Ground Movement: Detect convergence, settlement, and surrounding ground changes
  • Water Ingress: Identify leak locations through temperature anomaly detection
  • Structural Safety: Monitor lining strain and identify developing cracks or joints opening
  • Fire Detection: Rapid temperature rise detection for fire safety systems
Temperature accuracy: ±0.5°C
Fire detection: <30s
Coverage: Full circumference
