新形势下HFC接入网建设和改造的技术模式选择

Choice of Technological Patterns in Construction and Modification of HFC Access Networks under New Situations and Circumstances

随着三网融合的不断演进和"宽带中国战略"的启动,视听传播领域从技术、业态到运营模式等多个层面互联网化的特征日益凸显。新形势下,有线电视网络建设和改造如何选择正确的技术模式和演进路线,以兼顾历史投资和发展需要,是摆在众多运营商面前的一道难题。结合实际的案例,对当前主流的HFC双向接入技术从建设成本、开通成本、运维复杂度、接入带宽等多角度进行对比分析,最后提出在当前形势下网络建设及改造应选择的模式,供同行参考。

combined with actual examples, a comparative analysis is given on the present mainstream HFC network construction mode, bidirectional access technology in cost, bandwidth, comprehensive properties and many other ways. In the end, patterns in construction and modification of networks under new situations and circumstances will be put forward for the colleague reference.
