OptaSense QuantX

QuantX from OptaSense (Luna Innovations group) is a quantitative-grade distributed acoustic sensing (DAS) interrogator that turns standard single-mode fiber into tens of thousands of virtual vibration and strain sensors. In long-range mode it captures full quantitative phase and amplitude data over a span of up to 100 km — without amplifiers or special cables — making it one of the longest-reaching systems in its class on the market.

Applications

• Pipeline integrity monitoring — detection of leaks, third-party interference, and excavation works along the entire route
• Perimeter security for borders and critical facilities — “fenceless” surveillance over tens of kilometers
• Rail — train tracking, intrusion detection, and monitoring of infrastructure condition along the track
• Power — supervision of underground and submarine cables and transmission infrastructure
• Seismology and geophysics — linear-response measurements for scientific applications (earthquake monitoring, long-range surveys)
• Static monitoring of structural and ground strain (response from 0 Hz)

Key parameters

Quantitative DAS — data you can trust

First-generation DAS systems provided qualitative information that “something is happening at this location.” QuantX belongs to the quantitative generation (QDAS): it measures signal phase and amplitude with a linear response to the actual vibration and strain of the fiber, including the quasi-static range from 0 Hz. As a result, the data is suitable not only for event detection and classification, but also for engineering and seismic analyses — from interferometry to ground strain measurements. The adjustable gauge length allows the system to be matched to the parameters of an already-laid cable, so deployment often makes use of existing telecommunications infrastructure.
