HFC宽带接入技术应用研究

Research of the application of HFC broad-band access technology

随着宽带网络技术的发展,各种多媒体业务的出现,对下一代宽带接入网提出了新的要求,以满足大容量、高性能、丰富业务开展的需要。本文阐述了HFC网络宽带接入技术的基本原理、现状和主要应用,提出了用户接入的解决方案和解决原则,分析了需解决的问题、功能和实现方法,并以某接入的实例,说明了HFC网络在宽带接入的应用。结论证明:由HFC网络所提供的全业务网将是一种新型的宽带业务网,提供了一种实现宽带通信的良好方法。

This paper illustrates in detail the access to broad-band. Furthermore, some technological hallmarks of the HFC broadband access and the methods to solve the problem between the broadband service net and the consumers＇access are introduced. It also gives the selection principles about the broadband access technology. A project of Ethernet networking is discussed. The application of HFC broad-band access of Ethernet networking is also covered by analyzing a case.
