| 摘 要： | 综合布线中的屏蔽与非屏蔽问题 ,在网络布线过程中不可避免地要遇到。目前国际上(欧、美两大阵营之间 )存在着屏蔽系统与非屏蔽系统优劣的争论。针对要不要建设屏蔽局域网的问题 ,从两个方面来加以分析 :一是综合布线中屏蔽的目的、理想与现实的差距、先进性、用户信息及屏蔽与非屏蔽的误区方面 ;二是建设屏蔽局域网的几种因素。

| Abstract: | The problem about Screen Shield and Non-Screen Shield will fall across in process of network integrating lines. At present, there is a international discuss about good or bad of Screen Shield and Non-Screen Shield between Europe and America. Aiming at constructing Screen Shield Local Area Network, this paper presents a comprehensive analysis from two aspects: One is purposes, disparity of ideal-real life, advances,users' opinions, several mistakes about Screen Shield and Non-Screen Shield in integrating lines; Another is factors of constructing screen shield local area network. |
