Research on Key Technologies of Digital Signal Processing based on Optical Communication

With the updating of communication technology, optical communication system is developing towards high speed and large capacity. In order to maintain the continuous flow of information, all-optical network came into being. Firstly, the optical communication transmission system is introduced. Secondly, according to its principle, the receiver principle is analyzed concretely. Through data optical transmission with computer, based on digital signal processing technology, four technical supports of all-optical network are proposed. Practice has proved the advantages of all-optical network.
