摘要
首先论述了EoC的系列标准,然后在面向NGB的EoC技术需求白皮书的基础上对EoC技术的物理结构和物理层参数进行了分析,最后阐述了低频EoC技术和高频EoC技术的各自特点,并且对EoC技术在有线电视接入网中可能会出现的一些问题进行了分析和总结,为各地在进行EoC技术的选择时提供一定的借鉴意义。
A series of standards for EoC is firstly introduced, and then the physical structure and the parameter of physical layer based on the white paper for EoC technology demand for NGB are analyzed. At last, the characteristic of flow-frequency and high-frequency EoC are expatiated, and some problems which may be exposured in the CATV system for EoC are summarized. And it makes sense to the choice of variedly EoC standard in rebulding the network.
