Abstract
According to industry and vehicle information communications features, this paper design and realize Gigabit optical network central node to solve problem of vehicle communication bandwidth and real-time response. Use MAC layer logic of FPGA design central node, realize Gigabit vehicle exchange protocol layer of Ethernet-based passive optical network (EPON), use GMII interface to connect the Gigabit physical layer circuit. The Gigabit physical layer core uses high speed communication Gigabit SERDES. Then use exchange protocol to ensure the microsecond real-time exchange. The test data shows that the equipment is practical with features of wide bandwidth, high real-time exchange rate, high anti-electromagnetic disturbance ability and low cost.关键词
