| Abstract: | Ethernet passive optical network EPON is considered as the best solution for the "first mile problem". The article briefly introduces the structure and the basic working principle of EPON, and then discusses the differences of architectural positioning between the EPON system and the Ethernet standard based on the IEEE802.3ah draft. In this article the authors also analyzed the difficulties of its technologies and the respectively solutions to achieve it, including DBA (Dynamic bandwidth allocation), ranging, EPON security and burst mode receiver. |
