在中国国内各地的有线电视网络上，充斥着多种接入网技术，太多技术难免造成“选择性困惑”。本文作者构建了“周氏平面”，并利用该平面形象地描述了各种接入技术与基础网络设施之间的适应性关系，从而对运营商的技术选择和未来的技术演进提供了有益的帮助。

Variety of access technologies already existed in those cable networks around China. So many technol-ogies often make operators dropped in the"selectivity confusion”. This article will start from the most basic hierarchy of cable television network&applications, discusses the intrinsic connections between those various layers. Especially, the author created a kind of "Zhou Chart" to describe the relations between access technologies layer and network infrastructure layer. With this chart, the adaptability of various access technologies to the different network infrastruc-tures (i.e. matching) can be understood very easily and graphically, thus such a chart can be helps for operators how to select technology correctly and future network evolution path.
