Product Info
Introduction
The high-performance chirped DAS all-in-one adopts the chirped pulse demodulation scheme to realize and do the coherent fading suppression, which greatly improves the spatial resolution (2m), more sensitive, and higher signal-to-noise ratio.
Features
- Fast demodulation speed, capable of real-time demodulation of the entire fiber optic cable
- Spectrum signal real-time output
- 2-meter high spatial resolution
- More sensitive than coherent DAS
- Data can be read in real time via TCP service
Applications
- Oil and gas pipeline monitoring (anti-breakage, leakage)
- Petroleum and petrochemical measurements
- Border security
- Seismic monitoring
- High-speed vehicles, rail transit monitoring, etc.
