telegraph cables
Victorian communication lines
Telegraph cables are insulated wires designed to carry electrical signals over long distances, transmitting coded messages between telegraph stations.
The term often refers specifically to undersea cables laid across ocean floors to enable intercontinental communication: The first transatlantic telegraph cable was laid in 1858.
Before wireless technology, telegraph cables formed the backbone of global communications infrastructure.
