1、 摘 要 HFC 网络宽带综合业务为进入家庭建立了一个可靠的通道，解决了信息 高速公路最后一公里的瓶颈。 本文首先对宽带接入网的定义、主要技术及其主要优势作了探讨，接下 来又对 HFC 宽带接入网的技术问题进行了分析讨论，包括 HFC 接入网的定 义及其主要技术，重点研究了 HFC 接入网回传通道的噪声问题，以及为解决 噪声问题而采用的集中分配式 HFC 网络和 S-CDMA 电缆调制解调器等。 最后 对宽带接入网建设的一些问题进行了探讨，对 HFC 和 LAN 接入以及 ADSL 技术作了比较，并结合我国的接入网状况，提出了 HFC 宽带接入应采用的方 案。 关键关键词词 宽带接入网 HFC
2、 Cable modem S-CDMA II Abstract HFC broad band integration operation provides a reliable channel to family, solves the bottleneck problem in the last part of information highway. First this paper mainly makes the study to the definition of Broadband access network, and main technique and the main ad
3、vantages. And then it analyses and discusses the connection technology of HFC broad band. The HFC mainly includes the definition and its techniques. It emphasizes on the noise of HFC broad band in backhaul channel, and also studies the applied HFC broadband and S-CDMA cable model in order to wipe ou
4、t the noise. After the discussion of the problems in the HFC broad band construction, it compares the HFC with the technique of ADSL and connection of LAN, and then falls together with Chinese band connection status, HFC broad band connection should be applied in this way.
