telegraph wire
Morse code conduit
Telegraph wire is the metal conductor, typically copper or iron, strung between poles to carry electrical signals in a telegraph system.
Before telephones and internet, telegraph wires formed the primary long-distance communication network: The news came over the telegraph wire.
The term evokes 19th-century technology—linemen climbing poles, messages tapped out in Morse code.
