“光进铜退”推动宽带接入革命

Broadband Access Revolution Promoted by “Optical Access Replacing Copper”

随着互联网的持续快速发展,网上新业务层出不穷,用户对网络带宽要求越来越高,目前宽带接入技术铜缆ADSL已经成为用户与核心网之间的接入"瓶颈"。在目前形势下,综合考虑建设成本、业务需求、技术成熟度、竞争形势等多方面的因素,适时采用"光进铜退",最终实现FTTH势在必行。本论文首先对目前应用的几种宽带接入技术进行介绍,随后引出光进铜退的概念,并对其必要性、建设模式做了详细描述,最后对FTTH的系统结构进行了分析。

With the development of Internet, the ADSL technology with copper has become the bottleneck between the customer and backbone Network. This article first introduces a few of broadband access technology, and then leads to the concept of ＂Lght of Copper＂, finally detailed analysis is made on the structure of FRITH system.
