| Abstract: | A hardware-realized real-time Ethemet system based on multipoint-to-point passive optical network structure is designed and described in this paper. The physical layer functions of the central node and access node of the network are implemented by using FPGA. Besides, an experimental network connected with 16 access nodes and l central node is set up. By simulating CAN users, the feasibility and real-time property of the system is validated, whose real-time response is less than 200 . |
