The Key Technology Study on the Physical Communication Performance of the the EPON Upstream ZHANG JUNJIE , SHI JUN, HONG LIANG (Key Laboratory of Special Fiber Optics and Optical Access Networks (Shanghai University) Ministry of Education, Shanghai 200072)
Abstract: This paper studies the key technologies which affect the communication performance in the EPON system with a burst-mode in the uplink path. The solution to improve the performance is put forward using Verilog code, and the simulation results verify the code. The bit error ratio is less than 0.03% on the practical EPON test platform.
