用户光端机防范雷击的具体办法？

雷电不会从光纤进来，所以光端机被雷击主要是通过电源和支路电缆中传进。解决防雷的前提条件是机房的接地要好。机房接地电阻至少要要小于1欧姆。接地不好，后面采用什么方法都是空的。光端机一般都有工作地和保护地，从防雷的角度，工作地和保护地要分开接（有些厂家把工作地和保护地在光端机子架里接在一起了，这样不利于防雷击）。机房保护地在一点接入大地，并且保证接地电阻符合要求。机房接地符合要求以后，在机房电源和配线架（如VDF）上安装防雷保护装置，保护装置的接地接入保护地。机柜也接入保护地。接地和防雷保护装置做好以后，就可以防雷击了。我遇到过多起这样的案例，有的是是施工时没有按照规范做，有的是机房接地没有做好（有个例子，有个在贵州一座山上的机房，由于是石头山，没有土，机房接地电阻居然有50多欧姆，等于没接地，想了很多办法都没用，后来花了几百万将接地线装置引到山下，最后才解决问题）。

谢谢大虾,我又咨询了几个人,你的方法非常好,可惜我们领导不大重视
