摘要
Ethernet Passive Optical Network (abbreviated as EPON) has gained a lot of attention as an effective solution to broadband local access network. While it is a very cost-effective solution, it has some key technologies needed to develop, including upstream traffic synchronization. In the upstream direction, EPON is a multipoint-to-point network. In this paper, we present the principle and simulation of upstream synchronization, a process of finding a specific delay for every network unit, such that all upstream transmissions will arrive at the central office without collisions.
