摘　　要：双向化改造后的有线电视网络,既是广播电视信号的传输网络,也是宽带业务的承载网络,是有线电视运营商实现业务发展与转型的基础网络。其中有线接入网络是有线电视网络发展的关键,与用户带宽需求和有线接入技术的发展密切相关。通过调研当前国内外有线电视网络的发展现状、有线接入技术及标准的研究进展,分析了有线接入网络的发展趋势,最后对一种自主创新的吉比特同轴接入技术(HINOC)进行了介绍。After bi-directional renovation, cable TV network not only transmits broadcasting TV signals, but also carries bidirectional broadband services. It＇s the basic network that cable network operators achieve business development and transformation. Cable access network is the key point of cable network＇s development, and bounds up with subscriber＇s bandwidth requiremem and cable access technologies. The current situations of domestic and international cable TV networks, cable access technologies and standards was surveyed, then the develop trends of cable access network was analyzed. Finally, an indigenously-developed gigabit coaxial cable access technology HINOC was introduced.
