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 reduce costs by the midspan manufacturer, the midspans can be designed without the use of data transformers. Rather, midspans can include transmit/receive couplers that have blocking capacitors and divider trees for the insertion of power.
