PEC or Pan European Crossing is a fibre optic cable network that links the European Union and the United Kingdom. It has a submarine telecommunications cable system segment crossing the English Channel linking the United Kingdom, Belgium, and France.
One cable has landing points in:
The other cable has landing points in:
TAT-9 was the 9th transatlantic telephone cable system, in operation from 1992 to 2004, operating at 560 Mbit/s between Europe and North America. It was built by an international consortium of co-owners and suppliers. Co-owners included AT&T Corporation, British Telecom and France Telecom.
TAT-14 was the 14th consortium transatlantic telecommunications cable system. In operation from 2001 to 2020, it used wavelength division multiplexing. The cable system was built from multiple pairs of fibres—one fibre in each pair was used for data carried in one direction and the other in the opposite direction. Although optical fibre can be used in both directions simultaneously, for reliability it is better not to require splitting equipment at the end of the individual fibre to separate transmit and receive signals—hence a fibre pair is used. TAT-14 used four pairs of fibres—two pairs as active and two as backup. Each fibre in each pair carried 16 wavelengths in one direction, and each wavelength carried up to an STM-256. The fibres were bundled into submarine cables connecting the United States and the European Union in a ring topology.
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.
A cable landing point is the location where a submarine or other underwater cable makes landfall. The term is most often used for the landfall points of submarine telecommunications cables and submarine power cables. The landing will either be direct or via a branch from a main cable using a submarine branching unit. The branch can be several kilometres long.
Apollo is an optical submarine communications cable system crossing the Atlantic Ocean, owned by Vodafone. It consists of 2 segments North and South, creating two fully diverse transatlantic paths.
Atlantic Crossing 1 (AC-1) is an optical submarine telecommunications cable system linking the United States and three European countries. It transports speech and data traffic between the U.S., the U.K., the Netherlands and Germany. It is one of several transatlantic communications cables. It was operated by American company Level 3 Communications and Irish company Tyco International, until their respective mergers in 2017 and 2016 with other companies.
Yellow / AC-2 is a submarine telecommunications cable system linking the United States and the United Kingdom. The cable is wholly owned by Lumen in the US following its acquisition of Global Crossing. The original owners, which each owned two of the fibre pairs, gave this cable system different names, so it is known as both Yellow and AC-2. It has a capacity of 320 Gbit/s as of January 2007, upgradeable to 640 Gbit/s.
Tangerine is a submarine telecommunications cable system segment. It crosses the English Channel, linking the United Kingdom and Belgium.
RIOJA-1 was a submarine telecommunications cable linking the United Kingdom and Spain across the North Atlantic Ocean.
RIOJA-2 was a submarine telecommunications cable system linking the United Kingdom and Belgium across the North Atlantic Ocean/English Channel.
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 Western Europe is a telecommunications cable system with both submarine and terrestrial parts linking several counties in western Europe.
VSNL Northern Europe is a telecommunications cable system with both submarine and terrestrial parts, connecting England and the Netherlands.
Concerto 1 is a submarine telecommunications cable system in the North Sea connecting the UK, Netherlands and Belgium. Concerto 1 was built in 1999 by Alcatel for Flute ltd, part of the Interoute group.
ULYSSES is a submarine communications cable network divided into two sections: ULYSSES-1 and ULYSSES-2 that transit the English Channel and the North Sea, respectively. It carries telecommunications and internet signals to-and-from the United Kingdom to the continental European Union. It began service in 1997 and is owned by WorldCom International, BT, France Telecom and KPN.
SEACOM launched Africa's first broadband submarine cable system along the continent's Southern coasts in 2009. SEACOM is privately owned and operated.
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.
HUGO is a submarine telecommunications cable linking the United Kingdom, the Channel Islands, and France.
The Critical Foreign Dependencies Initiative (CFDI) is a strategy and list, maintained by the United States Department of Homeland Security, of foreign infrastructure which "if attacked or destroyed would critically impact the U.S." A copy of the 2008 list was redacted and leaked by WikiLeaks on 5 December 2010 as part of the website's leak of US diplomatic cables; no details on the exact location of the assets was included in the list. In September 2011, WikiLeaks published the unredacted copy of the list. The list's release was met with strong criticism from the US and British governments, while media and other countries have reacted less strongly saying that the entries are not secret and easily identified.
