摘要
基于同轴电缆的以太网数据技术(EoC)在国内广电网的接入网技术中已应用和发展多年,随着三网融合的推进,EoC技术成为下一代广播电视网(NGB)的主要接入网技术之一。介绍了EoC主流技术C-HPAV的技术要点,以及广电运营商在系统设计部署中的技术应用要点,最后分析了该标准后续的技术演进方向。
Ethernet technology based on coaxial cable (EoC) has been used for many years in the access network of cable network in China. With the development of the triple play, EoC technology has become one of the main access network technology in the next generation broadcasting network (NGB). The key technology of the C-HPAV which is the main technology of the EoC is introduced in this paper, and the main technical points in the system designing, operating and managing are analyzed. Finally, the evolution direction of the C-HPAV is analyzed.
