Is the transatlantic cable still used today?
Transatlantic telegraph cables were undersea cables running under the Atlantic Ocean for telegraph communications. Telegraphy is now an obsolete form of communication, and the cables have long since been decommissioned, but telephone and data are still carried on other transatlantic telecommunications cables.
How many transatlantic cables are there?
How many cables are there? As of early 2023, we track 552 active and planned submarine cables. The total number of active cables is constantly changing as new cables enter service and older cables are decommissioned.
How deep are the transatlantic cables?
Once out in the sea or ocean, submarine cables are laid in deep water where they can lie on relatively flat parts of the ocean floor, avoiding contact with large rocks. For example, trans-Atlantic subsea cables, which traverse the Atlantic Ocean, are laid at depths of ~13k feet (~4k meters) at their deepest point.
Where does the transatlantic cable come ashore?
PORTHCURNO CABLE STATION
John Pender intended to land it at Falmouth, hence the name of the telegraph company, but the high risk of damage from ships' anchors at the busy port changed his mind, and the cable came ashore at Porthcurno.
