摘　　要："周氏平面"采用了图形化的方式,诠释了接入技术与网络基础设施之间的适应性关系。本文在"周氏平面"的基础上,进一步阐述了"Cloonan区"的含义及其下边界的界定、"1×1"斜线对分布式接入技术的限制等内容,并解释了如何利用"光进铜退"扩展频谱以得到更高的速度和网络容量。据此,本文分别描述了DOCSIS技术、分布式的EoC和C-DOCSIS技术在"周氏平面"上的演进途径。The graphical “Zhou’s Plane” well explained the adaptabilities of the access technologies for network infrastructure. In this paper the author elaborated even further the meaning of ＂Cloonan Zone＂ and how to define its lower boundary, the restrictions of distributed access technologies （like EoC, C-DOCSIS and remote PHY etc.） by the 1＆#215;1 oblique line on “Zhou’s Plane”. The author also explained how to extend the spectrum so as to obtain much higher speed and improve network capacity by using “fiber deep”. After then, several detailed evolution paths were also described on ＂Zhou’s Plane＂, in terms of the centralized DOCSIS, distributed EoC and C-DOCSIS sepa-rately.
