摘要
A midspan device for providing power and data from a one-pair power sourcing equipment to a two-pair powered device is described. The midspan device is connected to the one-pair power sourcing equipment and takes a portion of the power from the power sourcing equipment to power a converter. The converter converts one-pair data into a two-pair data and forwards the converted data to the two pairs of the powered device. Another portion of the power from the power sourcing equipment is on a DC path and coupled through center tap transformers to provide power to the powered device.
