| 摘 要： | DOCSISV3．0是DOCSISV1．1／V2．0的扩展，它使有线电视HFC网络在扩展频谱、加大流量、增强功能方面有了重大突破，是CableModem接入技术的又一次重大进步。简单介绍DOCSIS研制背景，重点介绍DOCSISV3．0的主要特点，并对DOCSISV3．0的应用前景进行分析，认为EPON／GPON可能是电信网络改造的最佳方案，而双向HFC网络改造不宜采用EPON＋EOC方案，CableModem接入才是有线电视双向HFC网络改造的主流技术，能真正实现三重服务的同网传输。

| Abstract: | DOCSIS V3.0 is the extending of DOCSIS V1. 1/V2.0. It makes the HFC can perform better in spread spectrum, flow enlarging and function increasing, and it is a progress of the Cable Modem technology. This paper introduces the background, merits and the outlook of DOCSIS V3.0. It reckons the EPON/GPON as the best scheme of telecom transformation. And the HFC bi-directional network is not suitable to the EPON/GPON. Cable Modem is the mainstream technology of HFC transformation. |
