Aimed at the operation features of vehicle environment, designed a vehicle real-time fiber control network macro architecture based on Ethernet PON (EPON). Analyze switching mechanism of network macro architecture and time division multiplexing (TDM). The MAC design of center node was discussed. Then, through the test of data-transmit-receive and vehicle CAN bus, the stability and reliability have been proved, which has good practicability. The test results show that, compared with traditional customized ASIC chip design, the network have the character of upgrade-agility, small form, low power consumption and so on.
