新手问题多，大大们请讲解...

“点”是什么意思，经常看到3000 点的什么系统啊，60点的KTV系统等，这个点到底是什么？

点就是 指节点数，也可以简单的理解为接口数  比如说一个局域网有50台电脑 你可以说有50个点

工作区有多少个模块，就有多少个点。

<P>知道了，谢谢</P><P>那么0.4的线和0.5线及0.51的线使用效果有多大差别？</P>

一般网络线规以AWG24为多，线缆外皮上有标识的，0.51的线基本上说的就是AWG24号的线。6类线有些厂家用的是AWG23的线，就比AWG24要粗些了。

<P>真的太谢谢大大们了</P>
<P>那么在实际运用中，0.51，0.48和0.45可以互相替代不，不会对施工质量有什么影响吧？</P>

大大们，怎么没人解答了

哈哈,你不知道的还多呢

<P>不会吧，那大大们如果不想公开发表那可以发到我邮箱或给我悄悄话，我真的需要了解，否则出问题我陪死了</P>

最好是按照规矩来，不要乱用线  是什线就用什么线，你要知道，干扰无处不在 现在我们都还得选质量好的线去做工程，你却在这里说用什么线去替代  厉害哦

<P>呵呵，这是当然的，线是要用标准的</P><P>问题出在一些小工程并不用标准的线就可以了，工程队自己都要求我了，我能不给他们需要的嘛，但是有些工程说大也不大说小也不小，用标准的他们觉的贵没必要，不用标准想价格便宜点的又怕我偷鸡（供烂货），要我签定供货合同，所以我才要搞清楚，到时候出了问题他把责任往我这一推我不是挂了嘛，现在做供货商真苦</P>

<P>在线的直径上也省不了多少钱，用正规的吧！24AWG，也就是0.51</P>

<P>现在很困惑，0.51是标准的，可是现实的是我向世面上的商家们询问，他们都说0.5是标准，一舟的线我问他他也说超五类的标准线是0.5的，真的很困惑啊，到底标准线是数值上的0.51还是现实中商家们说（有几家还是名牌的）的0.5是标准的</P>

<P>大大们怎么没人回答啊</P>

<FONT color=#bb8c44 size=3>布线的标准太多</FONT>，<FONT color=#4474bb size=4>一下子记不住</FONT>，<FONT color=#d52b6f size=5>不知道客户</FONT><FONT color=#cc5233 size=6>会不会问</FONT><FONT color=#8dc43c size=7>这么方面的问题。</FONT>

<P>标准太多了啊</P>

<P>好怪异，我在线厂那看生产线，铜丝标准的305米，在被做成成品线时，只有290米，是不是因为线是绞着的状态所以缩短了距离？</P>

<P>大大们，那些标准的305米是成品线的长度还是铜线的原始长度？</P>
