摘　　要：在光纤工业专用网业务特点的基础上 ,对各种业务进行了划分 ,分析了物理层数据处理机制 ,确定了网上传输的时域帧结构和在物理层处理的流程 。A novel dedicated multimedia fiber industrial network (FIN) established by consulting the protocols and standards of FDDI II satisfies the specific requirements of real time data transmission. In this paper, the services of FIN are classified and the cycle frame structure is determined. The processing mechanism of the PHY sub layer is analyzed and the transmitting and receiving flow charts are presented. The data streams of a simulated frame processed in the PHY sub layer are illustrated on the basis of the service partition and processing schemes.
