阻燃交換機(jī)通信電纜色譜供從事通信工程的銷(xiāo)售商及通信愛(ài)好者、通信電纜色譜組成分序始終共有10種顏色組成，由5種主色和5種次色；5種主色和5種次色又組成25種色普，不管通信電纜對(duì)數(shù)多大，通常大對(duì)數(shù)通信電纜都是按25對(duì)色為一小把標(biāo)識(shí)組成。

通常阻燃ZRHJVV 交換機(jī)通信電纜分為：10對(duì)，20對(duì)，30對(duì)，50對(duì)，100對(duì)，200對(duì)，300對(duì)。。。。。2400對(duì)。

 50對(duì)通信電纜色譜線(xiàn)序：

說(shuō)明：50對(duì)的通信電纜要注意了，50對(duì)通信電纜里有2種標(biāo)識(shí)線(xiàn)，前25對(duì)是用“白蘭”標(biāo)識(shí)線(xiàn)纏著的！！后25對(duì)是用“白桔”標(biāo)識(shí)線(xiàn)纏著的！！

（注意：這25對(duì)用“白蘭”標(biāo)識(shí)線(xiàn)纏著）
