The industry analyst TeleGeography estimates that more than US$10 billion worth of new subsea cables will enter service between 20, adding to new installations over the previous five years with a combined price tag of US$9.2 billion. Most new deployments are being funded by the likes of Google, Amazon, Microsoft and Meta, which together now account for around two-thirds of all internet traffic-and a jaw-dropping 90% on the busiest trans-Atlantic links. Submarine installations back on the riseĪfter a lull in activity around a decade ago, the last few years have seen a rapid uptick in installations of submarine cables across all major routes. Global Links: The world’s oceans are home to more than 1.3 million km of optical fiber that provides crucial communications links all over the world. These underwater links-which combine ultrafast data transfer with the security and reliability needed to underpin such critical infrastructure-now carry 99% of the world’s telecommunications traffic. But the urgent need for extra bandwidth also extends to the submarine optical cables that provide the crucial connections between continents. The most tangible sign is in the access networks, with dedicated fiber connections now reaching out to homes and businesses to satisfy their increasing dependence on video platforms and cloud computing. Network operators are responding to that surging demand by accelerating plans to add capacity to their infrastructure. (An exabyte is 10 18 bytes, or a billion gigabytes.) According to the Ericsson Mobility Report, the amount of data consumed by the world’s population will more than triple over the next five years, extending beyond 900 exabytes per month by 2027. That trend shows no sign of slowing down, with new applications and services capturing attention and millions more people becoming connected to the internet every year. The spread of streaming services, the advent of 5G mobile networks and the rapid rise of video calling and virtual work during the COVID-19 pandemic boosted global internet usage by almost 30% per year between 20. The world’s growing reliance on mobile and digital technologies is driving a seemingly insatiable demand for data. This 2015 map was inspired by medieval and renaissance cartography and features a vintage map style containing sea monsters, cartouches and border illustrations.Network operators are laying more submarine cables with ever-higher capacities to support demand for data services. 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. 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.
