NEUBRESCOPE - Real-Time Distributed Acoustic Sensing

Combining the power of time-gated OFDR and industry-proven fiber optics, the NBX-S4000 Series enables high-resolution, long-range vibration and acoustic monitoring across critical assets.

NBX-S4000 Series

Turn Your Optical Fiber into a High-Resolution Vibration Sensor

The NBX-S4000 Series – including the NBX-S4100 and NBX-S4200 – transforms standard optical fiber into a powerful distributed acoustic sensor. By leveraging advanced Rayleigh-based interrogation, it delivers precise, real-time data on vibration, strain, and acoustic events across up to 120 km. Ideal for critical infrastructure like pipelines, bridges, tunnels, power plants, and security zones.

Your Questions About NEUBRESCOPE — Answered

What’s the difference between NBX-S4100 and NBX-S4200? The NBX-S4200 supports dual-channel fiber input and has higher interrogating capacity, whereas the NBX-S4100 is optimized for single-channel operation and streamlined integration with AI-based signal detection workflows.
Which industries benefit from the NBX-S4000 Series?

These systems are used in energy (e.g., pipeline monitoring), seismic sensing, perimeter security, transportation infrastructure, and research environments where continuous, distributed sensing is essential.

What type of sensing does the NBX-S4000 Series support?

The NBX-S4000 Series supports Distributed Acoustic Sensing (DAS) and Distributed Vibration Sensing (DVS), capturing acoustic, seismic, and vibration signals with high accuracy.

How is the NBX-S4000 Series deployed in the field? The system connects to standard single-mode or multi-mode optical fibers, typically installed along pipelines, tunnels, fences, or boreholes. Data is processed in real time or via post-analysis.
What does this device actually do ? simplified for non-engineers

Imagine turning a standard fiber optic cable into a long-distance sensing system — like giving it the ability to “feel” and “hear” what’s happening along its entire length. That’s exactly what the NBX-S4000 Series does.

Instead of placing thousands of physical sensors in the ground or on structures, this system uses light signals inside the fiber to detect tiny vibrations, movements, or changes in temperature. It can hear footsteps, detect leaks in pipelines, notice cracks forming in bridges or tunnels, or sense the vibrations caused by passing trains or construction work — all in real time.

Think of it as installing a super-sensitive nervous system along critical infrastructure. It helps you monitor long distances — even hundreds of kilometers — from one central location, making it faster, safer, and more cost-efficient to protect important assets like power plants, pipelines, or underground cables.
