阻燃交換機(jī)通信電纜色譜供從事通信工程的銷售商及通信愛好者、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)通信電纜色譜線序：
說明：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，前25對(duì)是用“白蘭”標(biāo)識(shí)線纏著的！！后25對(duì)是用“白桔”標(biāo)識(shí)線纏著的！！
（注意：這25對(duì)用“白蘭”標(biāo)識(shí)線纏著）
1對(duì)—白蘭 2對(duì)—白桔 3對(duì)—白綠 4對(duì)—白棕 5對(duì)—白灰
6對(duì)—紅蘭 7對(duì)—紅桔 8對(duì)—紅綠 9對(duì)—紅棕 10對(duì)—紅灰
11對(duì)—黑蘭 12對(duì)—黑桔 13對(duì)—黑綠 14對(duì)—黑棕 15對(duì)—黑灰
