All-in-One DAS Unit With Chirp Pulse Demodulation
This high-performance chirped pulse DAS all-in-one adopts advanced chirped pulse demodulation technology and integrates coherent fading suppression function. It achieves an ultra-high 2m spatial resolution, with higher sensitivity and signal-to-noise ratio (SNR) than conventional coherent DAS products, and supports real-time demodulation and data output for the entire optical fiber cable.
