PoE - Ethernet Magnetics

Ethernet Magnetics for Power Over Ethernet

The most common varieties of Ethernet employ differential signaling to transmit data over a network. Ethernet magnetics - most often coupling transformers - are used to help protect logic-level circuitry from overvoltage and noise by removing any common-mode signals carried by the twisted wire pairs. Power over Ethernet (PoE) systems can take further advantage of this strategy by supplying DC power as a common-mode bias over the same wires that carry data. Once the signal reaches an endpoint, the common-mode and differential signals are separated for use by an Ethernet appliance, called a "powered device" (PD). Learn More
