PowerInjector叫做电力注射器，意指它是一个中继设备，即能传输数据又能供电。通常用在交换机与终端（如你的无线AP）距离较远（通常超75米）的情况下，通过它相当于距离可以再扩展一倍。POE是通常是目前用得最多的，即通过它，可以将电源和数据都通过一根网线来实现。当然，它也要考虑传输长度、终端设备...
PoE供电器（PoE injector）也被称为中跨设备（midspan）、电源注入器（PoE charger）或是PoE适配器（PoE adapter)，主要通过网线（例如Cat5eCat6Cat6a等）将非PoE交换机和PoE受电设备（PD）相连进行工作。该设备一般适用于需要安装低功耗终端设备但缺少电源插座供电的地方。这一解决方案以较低成本的方式有效实现了网络...
