Abstract

In accordance with one or more embodiments, a method includes: receiving, at a stranded cable, a communication signal and a medium voltage power signal; propagating, by the stranded cable, the medium voltage power signal as an electrical signal utilizing an electrical return path; and propagating, by the stranded cable and responsive to the communication signal, guided electromagnetic waves, wherein the guided electromagnetic waves are guided by an interstice between uninsulated strands of the stranded cable and propagate within the stranded cable without requiring the electrical return path.
