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。
With the rapid development of IP services and the continuous emergence of various new services, high demands are placed on the access bandwidth and access capabilities of the network. In a variety of broadband access network technology, Ethernet passive optical network with high bandwidth, high efficiency and scalability and other features, access to existing and future multiple services, effectively solve the user access side of the bandwidth “ Bottleneck ”issue, becoming the best choice for broadband optical access. Introduced the hierarchical structure and working principle of EPON, and analyzed the technology of EPON realizing full service access.
