基于EPON的全业务接入

All-Service Access Based on EPON

随着IP业务的迅速发展和各种新业务的不断涌现,对网络的接入带宽和接入能力提出了很高的要求。在各种宽带接入网技术中,以太无源光网络具有高带宽、高效率和易扩展等特性,能够接入现有和未来的多种业务,有效解决了在用户接入侧的带宽“瓶颈”问题,成为宽带光接入的最佳选择。介绍了EPON的层次结构和工作原理,并分析了EPON实现全业务接入的技术。

The rapid development of new services such as IP services calls for better access bandwidth and ability of the network. The characteristics of broad bandwidth.high efficiency and good expensibility make EPON easily access to variable services on hand and in future. What＇s more, EPON solves the bottleneck of bandwidth for the user side well, so it becomes the best choice for wide band access with fiber among variable access technologies. This paper presents the architecture and principle of EPON and analyses the full-service access technologies for EPON.
