Columbus-III was a transatlantic telecommunications cable connecting Europe to North America.
Columbus-III entered service since December 1999 [1] [2] [3] and it's owned by over 30 carriers. Supported by 90 repeaters, it's 9833 km long.
After a 2009 upgrade, the capacity of the system between the United States and Portugal was increased from the original design capacity of 8 x 2.5 Gbit/s to 160 Gbit/s initially. The upgraded system could accommodate up to 320 Gbit/s with potential to go even further beyond. [1] [2] [3]
The cable was decommissioned in December 2020. [4]
TAT-8 was the 8th transatlantic communications cable and first transatlantic fiber-optic cable, carrying 280 Mbit/s between the United States, United Kingdom and France. It was constructed in 1988 by a consortium of companies led by AT&T Corporation, France Télécom, and British Telecom. AT&T Bell Laboratories developed the technologies used in the cable. The system was made possible by opto-electric-opto regenerators acting as repeaters with advantages over the electrical repeaters of former cables. They were less costly and could be at greater spacing with less need for associated hardware and software. It was able to serve the three countries with a single transatlantic crossing with the use of an innovative branching unit located underwater on the continental shelf off the coast of Great Britain. The cable lands in Tuckerton, New Jersey, USA, Widemouth Bay, England, UK, and Penmarch, France.
CANTAT-3 was the third Canadian transatlantic telecommunications cable, in regular operation from 1994 to 2010, carrying 3 x 2.5 Gbit/s between Canada and Europe. It branches to both Iceland and the Faroe Islands. It is out of normal service for international bandwidth and is currently operated by Føroya Tele to service oil platforms in the North Sea.
A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other. In the 19th and early 20th centuries, each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the 20th century, all cables installed used optical fiber as well as optical amplifiers, because distances range thousands of kilometers.
ATLANTIS-2 is a fiber optic transatlantic telecommunications cable connecting Argentina, Brazil, Senegal, Cape Verde, Spain's Canary Islands and Portugal. It is the first submarine cable to link South America and the African continent.
The Southern Cross Cable is a trans-Pacific network of telecommunications cables commissioned in 2000. The network is operated by the Bermuda-registered company Southern Cross Cables Limited. The network has 28,900 km (18,000 mi) of submarine and 1,600 km (990 mi) of terrestrial fiber optic cables, all which operate in a triple-ring configuration. Initially, each cable had a bandwidth capacity of 120 gigabit/s. Southern Cross offers capacity services from 100M/STM-1 to 100 Gbit/s OTU-4, including 1G, 10G and 40G Ethernet Private Line services.
Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long fibre optic mostly-submarine communications cable that connects the United Kingdom, Japan, India, and many places in between. The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. The system runs from the eastern coast of North America to Japan. Its Europe–Asia segment was the fourth longest cable in the world in 2008.
Hibernia Networks, alternately known as Hibernia Atlantic, was a privately held, US-owned provider of telecommunication services. It operated global network routes on self-healing rings in North America, Europe and Asia including submarine communications cable systems in the North Atlantic Ocean which connected Canada, the United States, the Republic of Ireland, the United Kingdom and mainland Europe. Hibernia managed cable landing stations in Dublin, Republic of Ireland; Coleraine, Northern Ireland; Southport, England; Halifax, Canada; Lynn, Massachusetts, United States.
SEA-ME-WE3 or South-East Asia - Middle East - Western Europe 3 is an optical submarine telecommunications cable linking those regions and is the longest in the world. Completed in late 2000, it is led by France Telecom and China Telecom, and is administered by Singtel, a telecommunications operator owned by the Government of Singapore. The Consortium is formed by 92 other investors from the telecom industry. It was commissioned in March 2000.
South East Asia–Middle East–Western Europe 4 is an optical fibre submarine communications cable system that carries telecommunications between Singapore, Malaysia, Thailand, Bangladesh, India, Sri Lanka, Pakistan, United Arab Emirates, Saudi Arabia, Egypt, Italy, Tunisia, Algeria and France. It is intended to be a complement to, rather than a replacement for, the SEA-ME-WE 3 cable.
Apollo is an optical submarine communications cable system crossing the Atlantic Ocean, owned by Apollo Submarine Cable System Ltd. It consists of 2 segments North and South, creating two fully diverse transatlantic paths.
TGN Atlantic (TGN-A) previously VSNL Transatlantic and TGN Transatlantic, is a submarine telecommunications cable system transiting the Atlantic Ocean. The cable has been in operation since 2001.
VSNL Northern Europe is a telecommunications cable system with both submarine and terrestrial parts, connecting England and the Netherlands.
JASURAUS was a 5.332 Gbit/s, 2,800 km optical submarine telecommunications cable that connected Port Hedland, Australia, to Jakarta, Indonesia, with a further interconnection to the APCN and which was decommissioned in 2012.
The Internet in South Africa, one of the most technologically resourced countries on the African continent, is expanding. The internet country code top-level domain (ccTLD) .za is managed and regulated by the .za Domain Name Authority (.ZADNA) and was granted to South Africa by the Internet Corporation for Assigned Names and Numbers (ICANN) in 1990. Over 60% of Internet traffic generated on the African continent originates from South Africa. As of 2020, 41.5 million people were Internet users.
Unity is a Trans-Pacific submarine communications cable between Japan and the United States that was completed in April 2010.
Iceland is among the top countries in the world in terms of Internet deployment and use. 99.68% of Icelanders used in the internet in 2021.
Europe India Gateway (EIG) is a submarine communications cable system that connects the U.K., Portugal, Gibraltar, Monaco, France, Libya, Egypt, Saudi Arabia, Djibouti, Oman, United Arab Emirates, and India.
The West Africa Cable System (WACS) is a submarine communications cable linking South Africa with the United Kingdom along the west coast of Africa that was constructed by Alcatel-Lucent. The cable consists of four fibre pairs and is 14,530 km in length, linking from Yzerfontein in the Western Cape of South Africa to London in the United Kingdom. It has 14 landing points, 12 along the western coast of Africa and 2 in Europe completed on land by a cable termination station in London. The total cost for the cable system is $650 million. WACS was originally known as the Africa West Coast Cable (AWCC) and was planned to branch to South America but this was dropped and the system eventually became the West African Cable System.
Africa Coast to Europe (ACE) is an optical-fiber submarine cable system serving 24 countries on the Europe, west coast and south Africa, managed by a consortium of 20 members.
MAREA is a 6,605 km long transatlantic communications cable connecting the United States with Spain. Owned and funded by Microsoft and Facebook, but constructed and operated by Telxius, a subsidiary of the Spanish telecom company Telefónica, it is the "highest-capacity submarine cable in the world" with a system design capacity of 200 terabits per second as of 2019.
