需要2.5g的，可以反向供电的POE交换机，至少八个口的，最好十个口

我目前了解到的，好像反向供电没有能做到2.5g的

大品牌都不做反向供电的poe交换机，不知为什么

而且我能买到的最大功率的反向供电就是90w的，用网线供电90w同时传输数据

poe大厂做的很多，2.5g的少

poe分离器?不知道会不会影响速度

看清楚,lz是要给交换机反向供电,不是在找poe交换机

就是poe交换机 本身也需要poe供电。。。。

poe供电又poe输出，那输入功率多少输出功率又多少，这个要求不是不可能，只是很傻

村村通用这种东西多 和电源要配套
lz可以去问问做过村村通工程的公司

poe的协议估计就没这个

这种都是魔改的吧，内部其实就是把网线当电线用，问题网线那点线经，功率大了不会烧吗？

poe交换机功率普遍都很大,靠poe通过网线给poe交换机本身供电不太靠谱

看到这里，突然想起当年装监控的师傅，网线里挑了两根接上了220v

后来自己维修的时候忘记了，拿钳子一剪

那酸爽……

应该是装监控用的吧？有的监控可以用网线供电
