Introduction
The Enhanced DAS All-in-One is able to realize full-phase real-time demodulation of the entire fiber optic cable, suppressing the coherent fading problem and outputting cleaner signals than the general-purpose DAS All-in-One.
Characteristics
- Highly integrated (DAS-Pro modules, industrial controllers, acquisition cards, etc.)
- Modular design allows selection of modules according to sensing distance
- Coherent fading suppression
- Fiber-optic cable full-area real-time demodulatio
Applications
- Oil and gas pipeline monitoring (prevention of external breakage, leakage)
- Petroleum and petrochemical surveying
- Perimeter security
- Seismic monitoring
- High-speed vehicle, rail transit monitoring, etc.
