三、综合布线常用介质介绍在综合布线系统中,使用最多的是各种不同类型的线缆,这些线缆构成了综合布线系统中信息传输通道的主要部分,因此线缆的性能对整个系统的性能有很大的影响.我们常用的线缆主要包括铜缆和光缆,光缆虽然可实现较高的传输带宽,但由于价格昂贵,故一般只用于一些干缆,而铜缆以其安装灵活、造价较低等特点一直被广为采用.目前所用的铜缆多为双绞线(Twisted Pairwire,简称TP).下面详细介绍一下双绞线的分类与选用.(一)双绞线的分类根据不同的衡量标准,双绞线可进行
Third, the common media used in the introduction of integrated wiring In the integrated wiring system, the most widely used is a variety of different types of cables, these cables constitute the main part of the integrated cabling system information transmission channel, so the performance of the cable for the entire system Performance has great influence. Our commonly used cables mainly include copper cables and optical cables. Although optical cables can achieve high transmission bandwidth, they are generally used only for some dry cables due to their high price. Features such as lower cost, etc. have been widely used. The copper cables currently used are mostly twisted pairs (TP). The following describes in detail the classification and selection of twisted pairs. (1) Classification of twisted pairs According to different metrics, twisted pair can be performed
