![]() ![]() This 2015 map was inspired by medieval and renaissance cartography and features a vintage map style containing sea monsters, cartouches and border illustrations. For example, one of my favorite Telegeography maps can be found at. You can explore Telegeography's Submarine Cable Maps for previous years just by changing the year in the map's URL. This storymap format also provides information on some of the new submarine cable builds which have taken place in each continent over the last year.Įach year's edition of the Telegeography Submarine Cable Map has a different design. As you scroll the page the map sidebar updates to provide more information about each of these regional hubs, providing details about the submarine cable companies with infrastructure in each hub. These inset maps provide a more detailed view of regional submarine cable hubs around the world. What is new for the 2022 Submarine Cable Map is that this year Telegeography has used a storymap format to help explain all this textual information in more detail.Īs you scroll through this year's version of the Submarine Cable Map the map pans and zooms to each of the smaller inset maps. Like last year's Submarine Cable Map this year's edition features lots of textual information, featuring both cable trivia and answers to FAQ's about cable suppliers and content providers. The new submarine cable map from Telegeography shows 486 cables and 1,306 landing stations. This includes all our telephone and Internet data. In the 21st Century submarine cables carry digital data. In the 19th Century the first submarine cables were laid to carry telegraphy traffic. Subsea cables carry telecommunication signals under the oceans, communicating information between different countries and regions of the world. In July 2017, it was launched for commercial services and is the longest submarine cable system in over a decade.Every year the telecommunications company Telegeography releases a new map to visualize the updated global network of undersea telecommunication cables which carry all our data around the world.The 2022 Submarine Cable Map has now been published. Frequently Asked Questions (F.A.Q.)Īsia-Africa-Europe 1 (AAE-1) is a 25,000 km submarine communications cable system from South East Asia to Europe. The electric core is a concentric assembly of inner conductor, electric insulation and protective layers often carry optical fibers for data transmission or temperature measurement, in addition to the electrical conductors. The purpose of submarine power cables is the transport of electric current at high voltage. What is the purpose of submarine power cables? These are called “submarine” because they usually carry electric power beneath salt water (arms of the ocean, seas, straits, etc.) but it is also possible to use submarine power cables beneath fresh water (large lakes and rivers). Submarine power cableĪ submarine power cable is a transmission cable for carrying electric power below the surface of the water. Despite its myriads benefits, internet access remains a hurdle in many developing countries, particularly in SSA where access rates in 2017 ranged from as low. If a submarine cable fault it is possible that internet services could cause disruption, but Internet is a decentralized network and when a node fails the information flow can re-route through other intact nodes and cables. What happens if submarine cable fault? There is a cable map around the world connecting all countries. ![]() You can see it better in our submarine cable map in 3D at top of the page. ![]() – The eighth and last layer, on the outside, polyethylene coating. – The seventh layer, a polyethylene terephthalate tape – The sixth layer, some braided steel wires. – The fifth layer, a waterproof aluminum barrier. – The fourth layer, a polycarbonate tube. – The third layer, a copper or aluminum tube. – The second layer, Vaseline that protects from water. There are up to eight layers in submarine cables, which we explain from the inside to the outside (contrary to the image that illustrates it) Everything around it is just layers and layers that protect it from breaking easily, waterproofing the entire cable or padding it. Although in photographs or images we can see them with a great thickness, the truth is that their diameter is approximately three centimeters. It will depend on the connection in question, but it is a fine and delicate material. In this post, you can see an interactive submarine cable map that you can use in a globe in 3D. In this case, they are much more affordable than the satellites themselves. They are options with many advantages over others such as satellites, for example. Virtually all communications today are made through submarine cables, more than 90% of them. Submarine cables allow us to transmit data through them to improve telecommunications services. ![]()
