Eagle DAS

The Eagle DAS turns the fiber running alongside a pipeline into a continuous acoustic sensor, detecting and locating leaks, digging, and tampering long before they escalate, across tens of kilometers from a single interrogation point.

• Leak signature detectionIdentifies the acoustic and pressure-transient signatures of pinhole and rupture leaks in real time.
• Third-party intrusion (TPI)Flags excavation, manual digging and vehicle activity along the right-of-way, with meter-level localization.
• Single-ended reachUp to 50 km per channel (100 km with optical repeaters) interrogated from one end.
• Event classificationCustom software discriminates genuine threats from background noise to minimize false alarms.

Using trackside telecom fiber, the Eagle DAS continuously tracks every moving train and listens to the rail itself, delivering position, speed and direction while surfacing developing track and wheel defects.

• Live train trackingReports exact position, speed and direction of all trains simultaneously, with no trackside power needed.
• Predictive maintenanceDetects rail defects, wheel flats and ballast degradation from their vibration signatures.
• Intrusion & rockfall alertsWarns of trespassers, cable theft and obstacles on or near the track.
• High acquisition rateUp to 400 kHz sampling captures fast, transient mechanical events.

A buried or fence-mounted fiber becomes an invisible, kilometers-long tripwire. The Eagle DAS detects, classifies and pinpoints intrusion attempts the instant they happen.

• Continuous perimeter coverageOne fiber protects a full perimeter with no blind spots or individual sensors to power.
• Threat classificationDistinguishes footsteps, vehicles, digging and fence-cutting to drive the right response.
• Precise event localizationLocates each event to within a few meters for rapid, targeted dispatch.
• Covert & passiveThe sensing cable is immune to EMI and invisible to intruders.

The Eagle DAS converts fiber into thousands of synchronised seismic channels, enabling high-resolution monitoring of seismic activity, slope stability and ground movement to protect people and assets.

• Dense channel arrayThousands of measurement points at channel spacing down to 0.2 m, far denser than conventional geophones.
• Early-warning capabilityDetects micro-seismic precursors to rockbursts, landslides and volcanic events.
• Harsh-environment readyEngineered to operate reliably in mines and remote field deployments.
• Real-time localizationPinpoints the source of seismic events along the fiber instantly.

Embedded or attached fiber lets the Eagle DAS listen to large structures around the clock, capturing the vibration signatures that reveal fatigue, cracking and load anomalies before they become critical.

• Whole-structure coverageA single fiber instruments an entire bridge, tunnel or highway segment.
• Damage & fatigue detectionTracks changes in vibration response that indicate cracking, corrosion or loosening.
• Traffic & load analysisMeasures traffic flow, axle loads and dynamic response in real time.
• Cost optimizationCondition-based maintenance replaces costly scheduled inspections.

The Eagle DAS turns the fiber already buried under wharves, along berths and inside submarine cable routes into a continuous sensing network, protecting the perimeter, the quayside and underwater cables of an entire port from a single interrogator.

• Perimeter & quayside intrusionDetects fence climbing, unauthorized access and movement in restricted zones, located to within meters.
• Submarine cable protectionFlags anchor drag and mechanical impact on underwater cables before they cause a fault.
• Berthing & mooring eventsCaptures vessel mooring and berthing in real time, including hard contacts against the quay wall.
• Single-interrogator coverageUp to 50 km of perimeter, infrastructure and cable monitored from one unit, with no powered electronics in the field.
