笔者从2007年小本毕业一直在惠州广电网络从事HFC网络方面工作,以多年来的工作经验,从HFC双向网络现状出发,分析了HFC双向网络平台的技术,包括HFC双向网的工作原理及其传输的基本方式;介绍了HFC网络要解决的四个关键技术的问题,并详细讨论了这四个问题;最后分析了HFC网络的带宽分配及HFC网络存在上行噪声及其解决方法。 I graduated from a small case in 2007, has been engaged in HFC network in Huizhou radio and television network work, with many years of work experience, starting from the current status of HFC two-way network, analysis of HFC bidirectional network platform technology, including HFC bidirectional network works and its The basic methods of transmission are introduced. The four key technologies to be solved by HFC network are introduced. The four problems are discussed in detail. Finally, the bandwidth allocation of HFC network and the uplink noise in HFC network are analyzed.
