Electrical wired communication appeared in the 19th century and enabled for the first time near-instantaneous communication over continental distances. Over the last two centuries, there has been a steady evolution from using electrical currents to using electromagnetic fields to transmit information over long distances. The discovery of low-loss optical fibers in the last few decades has enabled a dramatic increase in the rate of information transmission and, importantly, a considerable reduction in the cost of transmitted bits. The latter lead to a widespread democratization of information sharing. We will present an overview of the evolution of long-haul wired communication, from single metallic wires to optical fibers. The emphasis will be on the physical phenomena thought to have driven technological evolution and some historical events that may have played a role in the development of long-haul communication.
