Product Overview
DVS Coherent Receiver 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.Intradyne Coherent Receiver 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. 

Product Features
1.High SNR of coherent detection
2.Directly used in DVS system
3.No need to modify the algorithm
4.Low noise isolation power supply
5.Reduce system costs

Product Application
1.Distributed light based on amplitude

2.Demodulation Fiber Vibration Sensing(DVS)
