Issues encountered by customers
In certain specialized distributed fiber optic vibration monitoring applications, customers often require higher spatial resolution to facilitate more precise localization algorithms. Conventional DAS solutions struggle to achieve high spatial resolution. Under standard 80 MHz AOM systems, spatial resolution typically ranges between 6 and 10 meters. While 200 MHz AOMs can generate narrower pulses, they significantly reduce detection range, resulting in poor signal-to-noise ratios and increased acquisition costs. Is there a solution that enhances spatial resolution without raising acquisition costs or data volume?
How to resolve it?
Based on this, we have developed this Narrow-Pulse DAS All-In-One Hardware Unit. Equipped with an Narrow-Pulse DAS integrated module internally, it achieves modulation output with a 20ns pulse width and delivers 3-meter spatial resolution over a 10km distance.
Characteristics
- 3-meter spatial resolution at 10km distance;
- Pre-installed GPU cards provide richer hardware resources, better suited for running AI algorithms;
- Fast demodulation speed enables real-time phase demodulation of entire optical cables;
- Coherent fading suppression algorithm delivers purer spectral signals;
- Spectrum plots utilize phase information for real-time display, offering more responsive performance.
Applications
- Belt Conveyor Roller Health Monitoring
- High Spatial Resolution Distributed Fiber Optic Monitoring Scenario
