Claim:
1. A method, comprising: receiving, by a circuit, first electromagnetic waves guided by a core of a cable without requiring an electrical return path, wherein the first electromagnetic waves have a first non-optical frequency range, and wherein the core is opaque and thereby resistant to propagation of light waves along the core; converting, by the circuit, the first electromagnetic waves to first electrical signals supplied to a first digital subscriber line (DSL) device; receiving, by the circuit, second electrical signals from the first DSL device; converting, by the circuit, the second electrical signals to second electromagnetic waves; and sending, by the circuit, the second electromagnetic waves to an interface of the cable for guiding propagation of the second electromagnetic waves via the core of the cable without requiring an electrical return path, wherein the second electromagnetic waves are directed to a second DSL device, and wherein the second electromagnetic waves have a second non-optical frequency range.
