Abstract: 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.

Key words: fiber industrial network (FIN), service classification, cycle frame, PHY sub-layer
