摘要
分四个阶段讨论了利用ＨＦＣ网络开展多业务接入的过程。可以看出，利用ＨＦＣ接入方案，从最初传送模拟ＣＡＴＶ业务，然后过渡到数字ＣＡＴＶ业务和交互式ＶＯＤ业务，再进一步开展双向话音和数据业务，最终可通过ＳＤＶ网络形式实现视像＼话音＼数据等全业务的接入并为将来过渡到ＦＴＴＨ打下基础。
This paper describes the evolution process of a HFC network for accessing multi services by four stages. From the paper, we can find that using HFC network can gradually offers the analogue CATV , digital CATV and interactive VOD, then bidirectional telephony and data transmission , and final target is full services SDV network which can be a base for realization FTTH in the future .
