size="3">双绞线电缆中的导线是成对出现的，每2条为一对，并且相互扭绕。根据美国线缆规格(AWG)规定：双绞线中的导线全部应为4对，共8根，首先您要确定您的网络跳线是什么类型的。</font></font></div><div align="left"><font face="微软雅黑"><font size="3"> </font></font></div><div

align="left"><font face="微软雅黑"><font size="3">确定了类型，下面可以测试速度，一般100米的标准长度，测试速度达到了100Mbps，则表明是5类双绞线。若双绞线小于这个长度，否则测出的数据没有任何实用意义。</font></font></div><div align="left"><font face="微软雅黑"><font size="3">
