SUPPLYING POWER OVER FOUR PAIRS OF CONDUCTORS IN COMMUNICATION CABLE

摘要

A novel system for supplying power over a communication link, such as an Ethernet cable, having first and second wire sets each composed of two pairs of conductors. The system includes a power supply device, such as power sourcing equipment (PSE), configured for applying power to both the first wire set and the second wire set to deliver the power to a powered device.
