宁德联通与广电合作HFC项目分析

本文分析了宁德联通与广电合作的HFC项目,认为有线电视网采用HFC(Hybrid Fiber Coaxial)技术,以光纤作为有线电视传输干线,同轴电缆作为用户接入网,是一种理想的双向传输平台。不仅可以播送更多的电视节目,而且还可以实现多种增值服务,建设一个频带宽、抗干扰能力强、可靠性高的双向交互式网络,实现与计算机互联网、公用电话网、公用分组交换网等网络的互联提供综合信息服务业务,是解决信息高速公路最后一公里宽带接入网的最佳方案。

The study on HFC between Ningde Unicom and SVA

By studing the HFC cooperation project between China Unicom(Ningde) and SVA Group,the autor proposes an opinion that HFC (Hybrid Fiber Coaxial) technique is an ideal two-way transmission plat- form for wired TV signal.The technique uses optical fiberas trunk line,valued-added services and broadcast More TV programs.It's the optimal plan to build a broad-banded,anti-jamming,highly veliable and bidi- rectional interactire network,which connects the computer Intemet,public telephone network and pablic pack-switched network and provides synthetical information servies.
