EPON+EoC技术在HFC网络建设中的应用

The application of EPON+EoC technique in building HFC network

随着"三网融合"的逐步推进以及居民对电视节目的多样性的需求,广电有线网络也逐渐由单向传送广播电视传统业务向宽带业务等多种综合业务发展。在这进程中,EPON+EoC技术日趋成熟,本文简述了什么是EPON接入方式,什么是EoC调制技术,并结合实际,阐述了如何利用EoC技术充分利用楼内现有的同轴电缆资源,完成双向网络改造,如何利用EPON+EoC组网方式开展多种综合应用。

As the requirement of country＇s ＂three network convergence＂ and the demand ot the publlc＇s diversity TV Show, the IV cable network is developing from the single direction propagation of traditional TV show to the multiple service show accompany with the broadband and so on. In the procedure, the development of EPON ＋ EoC technique is mature. In the paper, what is the EPON access and EoC modulation technique is introduced. Combined with the actual service, it is shown that how to make use of the EoC technique to complete the double-direction reformation based on the coaxial cable network and develop the multiple service application by EPON ＋ EoC network.
