Abstract: A kind of high speed serial link (HSSL) communication technology using optical fiber as communication media is designed to meet the demand of high speed interconnection between multiprocessors in hard real-time distributed motion control systems. The structure of HSSL physical layer, the protocol of data transfer layer and application layer and the FPGA programming method are described in detail. The communication technology has been successfully used in the project of development on the step and scan optic lithography. Practice proves that it has many advantages such as high reliability, very small protocol overhead, strong immunity for electromagnetic interference, easy to programming and so on.
