The main idea is that some static wires are built with a fiber optic strand in the center to carry communications. This setup uses the outer wire to provide mechanical support and protection, while the center fiber optic path handles data transmission between locations along the span. That center fiber is what lets signals travel without relying on copper conductors, giving a dedicated communications link embedded in the line.

Copper core would imply carrying electrical current, not data. Stainless steel core serves as a strength member, not a communications path. No core would mean there’s no central element to carry a dedicated fiber, so it wouldn’t provide the fiber-based communications described.
