Abstract :
In this paper factors affecting accuracy of time synchronization in EPON are analysed and the scheme of time synchronization in EPON based on IEEE1588v2 protocol is designed and implemented by FPGA. Experimental result shows that the scheme is feasible and good time synchronization accuracy about 20 nanoseconds can be reached.
