热缩管 有什么作用？...

<p>我是布线文盲，问几个问题，见笑了！</p>
<p>1 在网络布线中，能用到热缩管吗？它的作用是什么？</p>

透明热缩管一般是用在保护标签的

1、热缩管很少用到。除非加固标签时，也很少人用。
2、超5类的水晶头就是常用的，一排8针的那种，6类的水晶头，在内部排列时分了2层，外表看也是8针排列。但手工制的6类水晶头，80%通不过福禄克的跳线模块测试。所以，6类跳线一般主张买原厂生产的跳线。
3、6类双绞线一般指非屏蔽的。
    超五类屏蔽线是超5类的，外面有屏蔽层，屏蔽线也很2大类，就不详细说了。

头一次听说

把货拿到手中就什么都明白了，热缩管另一作用接地时能用到

实际操作一下就很明白了

<p>听人说用热缩管保护线接头&nbsp; 更牢固 </p>

光纤得用啊  另外便签也可以用

热缩管应该是：对光纤熔接中熔接点的保护作用，防止空气中酸碱对于光纤的腐蚀。
