Some years ago I was contacted by the descendants of an English engineer who was working at the Long Island NY cable station of the German Atlantic cable via the Azores at the start of WWI. Back in the 1950s a family…

There are high voltage submarine cables for electrical power - these are used to cross rivers and lakes, for example. International cables, like the ones between the UK and the European mainland, are used for load…
This was long before there were any electronic devices to amplify or otherwise manipulate the signal. The telegraph signals were just short electrical pulses representing Morse code, with a positive voltage for a dot…
Copper communications cable were in use from 1850 until the 1980s, when they were replaced one by one with fiber. Almost all the copper cables ever laid are still in the depths of the ocean, as it's not worth salvaging…
All the way back to the early days of the cable industry in the 1800s, it was easier and safer to lay a cable along the coast of undeveloped countries than to try and run a landline on poles across rugged terrain. Both…
A short timeline: 1850 - first telegraph cable laid across the English Channel between England and France. 1858 - first Atlantic telegraph cable between Ireland and Newfoundland. 1866 - first permanently successful…
