谁知道在什么情况下用六类线呀？...

要看预算，有钱当然用好的。

2006年了，怎么样也得用六类了！

<p>用ibdn的超五类捻连线对</p><p></p><p></p>

<p>这还用讨论啊</p><p>钱多就用好的</p><p>没钱就凑合被</p>

<p>关键是预算，速度要高就用六类！</p>

关键是预算啊！！！！！！！！！！！！！

13F的兄弟联系一下我啊，咱们好象同缘。

里面好热闹哦！

主要是考虑网络设备的使用和用户的需求，如果没有千兆带宽的需要，超五类就够了，最好在超五类的基础上做出一些特殊部位的六类预算,升级也不会影响

<p>用六类，一步到位。</p><p>后期维护可以考虑我们的软件啊</p>

同意十二楼的观点。我曾经用六类线长度超过180米跑100M

<p>每弄过</p>

<p>如果公司对网络的要求不是很高的话&nbsp; 建议你用5E&nbsp;&nbsp;当然可以留下一些地方给6类&nbsp;&nbsp; 方便以后升级</p><p>如果公司对网络的要求很高的话&nbsp; 建议你考虑用光纤接入+小区+办公室这种类型</p>

就用6类吧 差不了多少

根据你系统要求来选择你的产品,还有以后升级

<p>我想用5类和6类的总成本的区别，一般现在都用100M的交换机，1000M的少，终端设备上网10M也够吧！内网访问100M 会好一点，1000M 出口！交换机也是一样，最终用户5个，我想买一下1000M的交换机，没有什么用途。100M也够用了。</p><p></p><p>以上是我个人的看法，实际上有经验的也可以提出来供大家参考，彼此学习，才能进步，才能更好的赚钱嘛！</p>

不要讨论了就用6类
