Content providers, such as Google, Amazon, Facebook and Microsoft, are investing and driving much of this new building boom in submarine cables. These include insets showing new countries which will soon be connected for the first time and the amount of new cables being laid in the different global regions. This boom will see in the next few years around 107 new submarine cables being laid around the world, adding over 400,000 kilometers of new telecommunication cable to the global network.Ī number of information insets along the bottom of the 2019 map help explain this new building boom. This year's map highlights the huge recent building boom in submarine cables. Every year Telegeography releases a new updated version of its map of the global network of undersea telecommunication cables. the 2019 Telegeography Submarine Cable Map has arrived. ![]()
