Telephone wires are the vital conduits of modern communication, carrying both voice calls and internet data into homes and businesses around the world. Composed of copper or other conductive metals and protected by plastic insulation, these ubiquitous cables have enabled the explosion of telecommunications over the past century and a half. Though often hidden from plain view, strung along poles or buried underground, telephone wires and the extensive networks they form are engineering marvels—transporting countless conversations and connections across vast distances. From powering old-fashioned landlines to delivering high-speed DSL internet, telephone wires remain essential infrastructure even in today’s wireless age. This article explores the history, composition, and functioning of these modest but mighty cables that wire the world together.
