Photonic 110 distributed optical fiber early warning system(DAS)
Inquire NowDescription
The Photonic 110 Distributed Optical Fiber Early Warning System (DAS) is an advanced solution for effective vibration monitoring across extensive distances. It excels in single-channel vibration monitoring up to 80KM and can achieve a remarkable 150KM in double-channel applications. The system is designed for rapid vibration detection, boasting the shortest monitoring period of just 0.3 seconds. Its sophisticated pattern recognition and classification capabilities allow it to self-learn environmental background noise, ensuring accurate identification and filtering of interference effects after systematic recording and classification training.
This technology leverages coherent Rayleigh scattering to provide distributed vibration sensing. The sensitivity of optical fiber to physical stimuli such as vibration, sound, and deformation enables it to detect subtle changes in refractive index and length due to external signals, thanks to the elasto-optical effect. This results in variations in transmitted signals, including phase, intensity, and frequency, ensuring precise monitoring and response.
