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.
The DVS integrated module of distributed fiber optic vibration sensing system integrates ultra-narrow linewidth light source, AOM acousto-optic modulator, pulsed EDFA, optical circulator, Raman amplifier, DVS coherent receiver module, etc., which only needs to be matched with a high-speed data acquisition card to make a set of DVS distributed vibration measurement system.
