双绞线对电缆(Twisted Pair Cable)中每对线的两根绝缘铜线是相互扭绞在一起的,其目的是减少串音和对噪声的敏感性。双绞线对电缆又分为屏蔽双绞线对(STP,Shielded Twisted Pair)、筛网状双绞线对(ScTP,Screened Twisted Pair)和非屏蔽双绞线对(UTP,Unshielded Twisted Pair)。
UTP所表示的就是UNSHIELDTWISTED PAIR无屏蔽的双绞线, 而STP就是SHIELD TWISTED PAIR有屏蔽的双绞线了 所以没有屏蔽的双绞线可以工作这是不争的事实 例如安防常见的”双绞线视频转换器”也是经常使用UTP线缆 但是面对复杂的弱电环境与极微小的信号时 能够有预算进行有屏蔽的系统建置将是较好的 举例:当你用94Dbspl/...

安徽蓝普特种电缆集团双绞线(Twisted Pair Cable) 是由两根相互绝缘的导线按照的规格互相缠绕(一般以顺时针缠绕)在一起而制成的一种通用配线,属于信息通信网络传输介质。 双绞线网是目前常见的连网方式。它价格便宜,安装方便,但易受干扰,传输率较低,传输距离比同轴电缆要短。 双绞线过去主要是用来传输模拟信号的,但...
双绞线(twisted pair,TP)是一种综合布线工程中最常用的传输介质,一般由两根22～26号绝缘铜导线相互缠绕而成,“双绞线”的名字也是由此而来。它的特点就是价格便宜,所以被广泛应用,如我们常见的电话线等。它是用来和RJ45水晶头相连的。 双绞线可分为非屏蔽双绞线(UTP)和屏蔽双绞线(STP)。 屏蔽双绞线电缆的外层由...
