Abstract
A device for communicating and providing power over a cable having at least two conductors comprises an inductor having two secondary windings and one primary winding, and a transceiver coupled to the primary winding of the inductor, the two secondary windings of the inductors being coupled to two of the at least two conductors of the cable. Further, a voltage signal provided by the secondary windings of the inductors to the conductors varies symmetrically from an average potential. The inductor of the device can also comprise two primary windings connected in series and two secondary windings connected in series, the secondary windings also connected to two of the at least two conductors in the cable, wherein the voltage signal provided to the two conductors from the secondary windings varies symmetrically from an average potential.
