DVS Coherent Receiver Module     


DVS coherent receiving module is mainly used for amplitude demodulation distributed optical fiber vibration sensor (DVS) applications. The module has the characteristics of high SNR of coherent detection, and the output signal is amplitude signal. It can be directly used in DVS system without modifying demodulation algorithm; On the basis of coherent detection with high signal-to-noise ratio, the analog signal is denoised inside the module to maximize the signal-to-noise ratio, which can reduce the application of the system optical amplifier module and reduce the system cost.
