FortSense Ultra
Distributed Acoustic Sensing (DAS) System
FortSense Ultra transforms standard single-mode fiber optic cables into thousands of virtual microphones. Using Coherent OTDR technology, it detects and classifies acoustic vibrations along the entire length of the fiber in real time — delivering enterprise-grade perimeter security and infrastructure protection in a compact 2U chassis.

Enterprise-grade distributed acoustic sensing
Technical Specifications
Detects & Classifies
Coherent OTDR
Coherent OTDR (C-OTDR) is the optical technique behind DAS — it turns the fiber itself into a continuous, fully passive acoustic sensor.
High Precision
Pinpoints events to within ±4 meters anywhere along the sensing fiber.
Simple Integration
Connects over Ethernet and integrates with SCADA and VMS platforms out of the box.
SIL-2 Certified
Meets the IEC 61508 functional safety standard for critical infrastructure.
Configurable
Acquisition frequency is tunable from 10 Hz to 2,000 Hz to match each application.
Application Possibilities
A single FortSense Ultra interrogator protects long, distributed assets across a wide range of environments.
Oil & Gas Pipelines
Detect third-party interference, leaks, and intrusion along buried or surface pipelines.
Border Security
Continuous monitoring of extended borders with no power or electronics in the field.
Perimeter Security
Real-time detection of cutting, climbing, and digging at fences, walls, and boundaries.
Railway Monitoring
Track intrusion, rockfall, and asset health along rail corridors.
Highway Monitoring
Monitor traffic flow and roadside events across long highway sections.
Telecommunications
Protect fiber routes and detect third-party digging before cables are damaged.
Power Transmission
Safeguard transmission corridors and detect tampering with towers and lines.
Seismic Monitoring
Capture vibration and seismic activity along the full length of the fiber.
How FortSense Ultra Works
Standard single-mode fiber becomes the sensor. The FortSense Ultra interrogator analyzes back-scattered light in real time and streams classified events to the FortSense UI software over Ethernet.
Single-mode Fiber
Up to 50 km of standard fiber acts as a continuous acoustic sensor.
