摘　　要：广播电视网络拥有大量的传统HFC入户网络线路,在宽带中国和三网融合背景下,是要采用FTTH还是继续发挥同轴电缆的宽频特性实现宽带提速,这是摆在每个广播电视网络运营企业面前的一个极其重要的技术决策问题。本文通过结合佛山广电网络在DOCSIS 3.1技术方面的实网试点案例和经验,阐述了在同轴电缆网络上实现千兆以上宽带接入的可行性,希望能为各广播电视网络运营企业提供技术发展决策参考。With the strategy of ＂Broadband China＂ and ＂Broadband Guangdong＂, telecom operators increase the broadband speed, and carry out fiber network accessing transformation based on FTI＇H around the nation, in order to achieve MB bandwidth and even Gigabit bandwidth of households. The cable corporations have a large number of traditional HFC access networks. It is urgent for cable corporations to decide FTTH or coaxial cable to speed up broadband. This paper presents a gigabit broadband accessing scheme based on coaxial cable network, according to the application of DOCSIS 3.1 in Foshan Cable Network Corporation. It is sincerely hoped that these experiences provide reference for others.
