Abstract:
A midspan power sourcing equipment (PSE) for operation with power over Ethernet (PoE). The midspan PSE provides powering over wire pairs that are also used for data communication. To ensure compatibility with legacy Ethernet devices, the ports used for transmission of data are designed with a low effective impedance at a frequency of operation.
