综合布线是信息网络系统的关键环节之一,为了保证信息网络系统高速、稳定的运行,选择高质量、高性能的线缆就显得尤为重要。

线缆的选择应根据系统的要求、技术性能、投资概算等因素综合考虑,但在布线系统中应首先确定是使用线缆的类别和布线的结构(非屏蔽线缆、屏蔽线缆、光缆或几种混合使用)。线缆通常使用带有绝缘层的导线并使用一层或多层塑料外皮。而线缆中通常由2到3600个线对组成。大对数线缆通常用于主干布线系统,它们适合在语音和低速率数据传输中使用。这些线缆在干线和水平(集线器到桌面)布线系统应用中的最大长度在最新GB 50311-2007中有详细的说明。需要注意的是这些最大长度限制适用于所有的媒介。它们并没有考虑由于网络使用的线缆类型和协议类型的不同而造成性能方面的差异的影响。实际上,最大线缆长度将取决于系统的应用、网络类型和线缆的质量。
