Abstract
A power over one-pair Ethernet approach. A data transformer is coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. The data transformer enables a network device to transmit and receive data with a link partner device via the single conductor pair. Power transmission over the single conductor pair is enabled through the coupling of a power over Ethernet module to the single conductor pair using a diode that can be paired with a zener diode.
