广电接入网技术发展现状与趋势探讨

On the Development Status and Tendency of Cable Access Network Techniques

概述了三网融合形势下广电宽带接入网技术的发展现状与趋势。在光传输改造部分,通过相关技术对比,结合国外广电相关技术发展趋势,认为EPON1、0GEPON将是我国广电接入网光传输部分的主流发展技术。在用户接入改造部分,认为广电仍将以同轴电缆为主要接入介质,分析了现有EoC技术及其近期出现的两个重要收敛,最后介绍了5种新型EoC技术。

The paper mainly focus on the development status and tendency of cable access network techniques. Firstly in the optic section, through the comparison of related PON technologies and the consideration of American cable access network development tendency, we conclude that EPON and 10GEPON should be a mainstream option for China cable access network. Then, in the user access network, we propose the insist on the deployment of coaxial cable plant. Finally, two important convergence in traditional EoC were presented, and also five kinds of novel EoC technologies.
