Abstract
A system and method for enabling power applications over a single conductor pair. In one embodiment, data transformers are coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. Power is injected onto the single conductor pair after the DC blocking elements and power is extracted from the single conductor pair before the DC blocking elements. Saturation of the data transformers by the injection of power onto the single pair is thereby prevented.
