Power over Ethernet (PoE)  is exactly what it sounds like: a way to deliver DC power and Ethernet data over the same standard network cable . Instead of running an Ethernet cable and  a separate power cable (plus an outlet or power supply), PoE lets you install and operate compatible devices using one cable  from a PoE switch or injector. In the world of flight simulation hardware , that simplicity translates into something every integrator and prime cares about: faster build
