Their popular print Submarine Cable Map, this year sponsored by Telecom Egypt, is currently available to order as a physical art piece and is being distributed at ITW 2021. Faced with the prospect of ongoing massive bandwidth growth, owning new submarine cables makes sense for these companies.Ĭable enthusiasts have another opportunity to enjoy TeleGeography’s cartographic stylings. The amount of capacity deployed by private network operators-like these hyperscalers-has outpaced internet backbone operators in recent years. In the late 1990s, an influx of entrepreneurial companies built lots of private cables and sold off the capacity to users.īoth the consortium and private cable models still exist today, but one of the biggest changes in the past few years is the type of companies involved in building cables.Ĭontent providers such as Google, Facebook, Microsoft, and Amazon are now major investors in new cables. Cables were traditionally owned by telecom carriers who would form a consortium of all parties interested in using a cable. It’s fantastic to share our findings with the world in a free-to-use, universal resource for the industry.”īeneath the surface, TeleGeography’s popular map captures decades of network history. The data in this map were provided by EMODnet human activities.“We’re continually updating this interactive tool as the cable landscape develops. Submarine Cable Map by TeleGeography Map gallery of submarine cable. Click on one of the cables to learn more about its type, length, capacity, when it was installed and who maintains it. In August 2021, Google and Facebook announced that they would develop a subsea cable. The map of the week features a schematic representation of the submarine communication cables that cross European waters. Submarine telecommunication cable networks cost billions to install 1 and need constant monitoring and repair, as they may be broken or damaged by trawl fishing, anchors, earthquakes, submarine landslides and even shark bites 2. However, this capacity comes at a significant price. These fibre-optic cables have the capacity to transmit data at a staggering 200 terabits per second 1, which vastly outpaces today’s satellite radio transmission (around 1 gigabits per second), making them the preferred means of communication. Subsea cables carry telecommunication signals under the oceans, communicating information between different countries and regions of the world. While these early cables consisted of insulated copper wires, which were simply dropped on the seabed, current generation submarine cables consist of optical fibres covered by many protective layers buried in the seafloor 2. Every year Telegeography releases a new map of the huge global network of undersea telecommunication cables which carry all our data around the world.The 2021 Submarine Cable Map has now been published. Flat versions of the map are delivered to you rolled in a tube and ideal for hanging on. Submarine cables have a long history starting with the first commercial submarine telegraph cable in the English Channel in 1850, closely followed by the first transatlantic cable in 1866 1. 2021 Submarine Cable Map (free shipping) This edition, sponsored by Telecom Egypt, depicts 464 cable systems and 1,245 landing stations that are currently active, under construction, or expected to be fully-funded by the end of 2023. With over 99% of international internet and telephone traffic passing through submarine telecommunication cables 1, they are a vital though often forgotten part of today’s digital society. Whenever you access a website hosted on a foreign server, chances are high that the information you are receiving travelled through the depths of the ocean.
