The World's Infrastructure
Needs Better Eyes
Critical Infrastructure is Blind
Pipelines, railways, and power corridors span thousands of kilometers with little to no real-time sensing. Failures go undetected for hours — causing catastrophic damage.
Conventional Sensors Fall Short
Point sensors require enormous deployment costs, frequent maintenance, and leave massive gaps in coverage. They simply cannot scale to the size of modern infrastructure.
The Network Already Exists
Billions of kilometers of fiber optic cable are already buried worldwide — yet they carry only light, not intelligence. The sensing network of the future is already in the ground.
“What if every fiber optic cable could hear a footstep, detect a leak, or sense a tremor — automatically?”
— The LaseQ Systems Vision
Distributed Acoustic Sensing
DAS turns a passive fiber optic cable into thousands of virtual microphones, each separated by less than one meter, all monitoring simultaneously.
Laser Pulse Injection
Ultra-short coherent laser pulses are launched into a standard fiber optic cable. No hardware modifications to the cable are needed.
Rayleigh Backscattering
As the pulse travels, natural impurities scatter a tiny fraction of light back toward the source. This backscatter is our data — a continuous acoustic fingerprint.
Phase-Sensitive Detection
Our interrogation unit measures phase shifts in the returning light with picosecond precision — detecting disturbances as small as nanometer-scale fiber vibrations.
AI-Powered Classification
Proprietary signal processing and machine learning models classify events in real time: pipeline leaks, vehicle crossings, seismic activity, and more — with sub-meter accuracy.

The DLID Framework
Every LaseQ Systems system is built around a single four-word mandate: Detect. Localise. Identify. Decide. This is DLID — our technology philosophy and the engineering specification that every product must satisfy. It also names the underlying architecture: Distributed Laser Intelligence and Decision-making.
Detection
Sensing physical events — acoustic, seismic, and structural — with sufficient sensitivity to distinguish real events from environmental noise. The entry point of the intelligence chain.
φ-OTDR · ≤100 kHz linewidth laser · sub-nanostrain sensitivity
Localisation
Determining precisely where along the fiber an event occurred. Sub-metre spatial resolution over distances exceeding 100 km. Without localisation, detection has no operational value.
OTDR time-of-flight · interferometric phase analysis · <1m spatial resolution
Identification
Classifying the detected event into operationally meaningful categories — pipeline leak, human intrusion, train anomaly, structural failure. This is the AI layer that converts signal into meaning.
Edge AI classification · acoustic signature library · real-time inference · no cloud required
Decision
Delivering operator-ready intelligence — prioritised alerts, confidence scores, and recommended responses. Not raw data. Actionable intelligence with context.

From City to Seabed — One Fiber Network
A single continuous fiber cable becomes a live sensing network across terrestrial, coastal, and offshore environments simultaneously.
One Platform.
Endless Applications.
Our DAS technology addresses multi-billion dollar markets across energy, defense, transport, and smart city sectors.
Pipeline Integrity
Detect leaks, third-party intrusions, and corrosion events along oil, gas, and water pipelines — before they become disasters.
Railway Monitoring
Monitor track defects, unauthorized access, and structural anomalies across entire rail networks in real time.
Border & Perimeter Security
Deploy invisible acoustic fences across vast borders. Detect footsteps, vehicles, and tunneling activity with AI classification.
Seismic Monitoring
Turn urban fiber networks into dense seismograph arrays, providing unprecedented earthquake early warning and geological research data.
Data Center Cooling
Acoustic monitoring of cooling infrastructure within hyperscale data centers — detect pump failures, vibration anomalies, and inefficiencies.
Smart City Infrastructure
Monitor bridges, tunnels, and underground utilities using the city's existing fiber network as a city-wide structural health sensor.
ISR: Intelligence, Surveillance & Reconnaissance
Enable persistent, wide-area acoustic intelligence across strategic corridors — detecting troop movements, vehicle convoys, and subsurface activity without deploying additional hardware.
Bio-Sensing
Apply distributed acoustic sensing to biological environments — detecting physiological acoustic signatures, monitoring medical infrastructure, and enabling fiber-based biosensing for healthcare and life sciences research.
Why LaseQ Systems
DAS is not new. Our technology is. We've rebuilt the stack from the photonics layer up to deliver performance no off-the-shelf system can match.
Proprietary Interrogation Hardware
Our interrogator unit achieves phase sensitivity and dynamic range beyond commercially available alternatives — engineered from first principles — from laser linewidth and coherence length through to edge AI inference.
Real-Time AI Classification
On-edge ML models classify acoustic events with sub-second latency, distinguishing between dozens of event types without cloud round-trips.
No New Infrastructure Required
LaseQ Systems works with standard single-mode fiber already in the ground. Deployment is a connection, not a construction project.
Proven in Harsh Environments
Validated across temperature extremes, high-EMI zones, and subsea conditions — where conventional sensor systems fail.
Indigenous. Sovereign. Compliant.
Built in Hyderabad for Indian infrastructure conditions. LaseQ Systems operates entirely at the edge — no foreign cloud dependency, no foreign infrastructure requirement. Designed for IDDM certification and GeM procurement from day one.
