摘　　要：基于HFC(hybrid fiber-coaxial)网络结构,利用线缆调制解调器(cable modem, CM)实现宽带接入,可以充分利用现有的有线电视网络资源提供的对Internet的高速数据接入服务;在HFC的数据通信系统CM中用IP协议,可以很容易扩展开通基于IP的业务;介绍了HFC宽带接入的关键技术;提出了一种HFC宽带接入系统方案,并分析了制约HFC接入技术发展的因素.Based on HFC net structure, we can realize broad band access by using cable modem. It can make the best use of CATV net sourse in existence to supply the high rate data access service to Internet . Because IP protocol is adopted in cable modem system, it is more easy to expend the business. In this paper,the key technics about HFC broad access are introduced and a kind of system scheme are brought forword. Some factors that restrict the development of HFC are also introduced in this paper.
