DVS coherent receiver module
We have developed a DVS coherent receiver module for amplitude demodulation distributed fiber-optic vibration sensing (DVS) applications. This module not only has the characteristics of high signal-to-noise ratio of coherent detection, but also the output signal is amplitude signal. It can be directly used in the DVS system without modifying the demodulation algorithm; on the basis of the high signal-to-noise ratio of coherent detection, the analog signal is denoised inside the module, which can improve the signal-to-noise ratio as much as possible, and can reduce the application of the system optical amplification module , reduce system cost. It is very suitable for distributed fiber-optic vibration sensing (DVS) systems based on amplitude demodulation.
