Here is a list of submarine cables that have already been retired. So, if operational costs exceed revenues, they might be decommissioned ahead of time. However, their lifetime depends on their revenues. Submarine communications cables are designed to last about 25 years. Here is a list of the number of cables in service over the last decades, according to TeleGeography’s submarine cables map. The number of submarine cables worldwide has grown steadily over time. However, these technology giants are only dominant users in the trans-Atlantic route, not in the Europe-East Asia route. They account for two-thirds of all used international capacity. It is interesting to note that giant content and cloud service providers - Google, Facebook, Amazon and Microsoft - have surpassed carrier networks in international bandwidth usage. It has grown at a compound annual rate of 45% between 20. ![]() However, the region that has experienced the most rapid growth of international bandwidth is Africa. Medusa Submarine Cable System (2024), connecting Algeria, Egypt, France, Greece, Italy, Morocco, Portugal and Spain.Īccording to TeleGeography’s State of the Network report (2022 edition), capacity has grown across all regions.Bifrost (2024), connecting Guam, Indonesia, Philippines, Singapore and the United States.Trans Adriatic Express (2023), connecting Albania and Italy.Firmina (2023), connecting the United States to Brazil, Uruguay and Argentina.Galapagos Cable System (2023), connecting continental Ecuador and the Galapagos Islands.2Africa (2023), connecting 33 countries in Africa, the Middle East and Europe. ![]() Asia Direct Cable (2023), connecting China, Japan, Philippines, Singapore, Thailand and Vietnam. ![]() PEACE, short for “Pakistan & East Africa Connecting Europe” (2022), connecting Singapore, Pakistan, Kenya, Egypt and France.New submarine communications cables are expected to enter service during the following years. Moreover, the list of submarine cables continues to grow. EllaLink (2021), connecting Brazil to Portugal.Scylla (2021), connecting the United Kingdom and the Netherlands.Curie (2019), connecting California and Chile.Some of the submarine cables created during the past few years are: The need for new undersea cables increases as international bandwidth demand continues to grow. The oldest submarine cables still in service today are Denmark-Sweden 15, Rønne-Rødvig and Scotland-Northern Ireland 1 - in operation since 1989. Because an attempt to achieve faster operation destroyed it due to excessive voltage. However, that first transatlantic telegraph cable was only operational for three weeks. They connect regions and countries to provide high-speed Internet access.Īs a curiosity, it is worth mentioning that the first submarine cable was built in the 1850s to carry telegraphy traffic. Submarine cables or submarine communications cables are optical fiber cables that lay on the sea bed to carry data traffic across oceans and seas. 3.1 Retired cables What are submarine cables?
