telegraph cable
Transatlantic message conduit
A telegraph cable is a wire or bundle of wires used to transmit telegraph signals over long distances.
The term typically refers to submarine cables laid across ocean floors, which enabled near-instantaneous communication between continents in the mid-nineteenth century: The first successful transatlantic telegraph cable was completed in 1866.
On land, telegraph cables strung between poles carried messages across countries and territories.
