随着范围内越来越多的工厂采用以太网进行连接，人们也就愈发需要优化过程边缘的配电。一个自然而然的选择方案便是重新使用以太网供电(PoE)技术为以太网连接设备供电。PoE技术的优势在于它使用相同的电线进行电力和数据传输，从而节省了安装和总接线成本。为此，PoE电源通过将48伏连接到一对以太网变压器的中心抽头以及与另一对相类似的返回路径的方式，耦合到数据线中。然后，电源会在具有类似拓扑结构的设备上去解耦。

但是对于采用线形拓扑结构的工业以太网来说，以太网通信的25MHz工作频率可用于电源输出，因此可以在发射端耦合输出。在这种情况下，发射器将会受到来自接收器通道通信标准的噪声的干扰。

为此，EtherCAT P（对EtherCAT的扩展）采用了一个简单的电感电容(LC)滤波器，以确保在进入电源树之前能够阻止100BASE-T发出的25MHz信号。
