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.
A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858.
Submarine cable is any electrical cable that is laid on the seabed, although the term is often extended to encompass cables laid on the bottom of large freshwater bodies of water.
Sound Surveillance System (SOSUS) was the original name for a submarine detection system based on passive sonar developed by the United States Navy to track Soviet submarines. The system's true nature was classified with the name and acronym SOSUS classified as well. The unclassified name Project Caesar was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. The name changed to Integrated Undersea Surveillance System (IUSS) in 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems. The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance Pacific, and personnel were able to wear insignia reflecting the mission.
Mystic class is a class of Deep-Submergence Rescue Vehicles (DSRVs), designed for rescue operations on submerged, disabled submarines of the United States Navy or foreign navies. The two submarines of the class were never used for this purpose, and were replaced by the Submarine Rescue Diving Recompression System.

A submarine power cable is a transmission cable for carrying electric power below the surface of the water. These are called "submarine" because they usually carry electric power beneath salt water but it is also possible to use submarine power cables beneath fresh water. Examples of the latter exist that connect the mainland with large islands in the St. Lawrence River.
Wunderwaffe is a German word meaning "wonder-weapon" and was a term assigned during World War II by Nazi Germany's propaganda ministry to some revolutionary "superweapons". Most of these weapons however remained prototypes, which either never reached the combat theater, or if they did, were too late or in too insignificant numbers to have a military effect. The V-weapons, which were developed earlier and saw considerable deployment, especially against London and Antwerp, trace back to the same pool of highly inventive armament concepts. In the German language, the term Wunderwaffe generally refers to a universal solution which solves all problems related to a particular issue, mostly used ironically for its illusionary nature.
A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and tracking faint contacts, such as quiet, low noise-emitting submarine threats, or seismic signals.
Statnett is a Norwegian state owned enterprise responsible for owning, operating and constructing the stem power grid in Norway. The company has its headquarters in Oslo, Norway.
The Telstra Endeavour is a submarine cable connecting Sydney and Hawaii. The cable went live in October 2008, with a capacity of 1.28 terabits per second in the future It was proposed on 28 March 2007 by Telstra, the largest telecommunications carrier in Australia.
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.
PIPE Pacific Cable (PPC-1) is a 6,900 km submarine cable laid by PIPE Networks. It runs from Cromer, New South Wales, in Australia, to Piti, Guam.
Telecommunications in Angola include telephone, radio, television, and the Internet. The government controls all broadcast media with a nationwide reach.
BritNed is a 1,000 MW high-voltage direct-current (HVDC) submarine power cable between the Isle of Grain in Kent, the United Kingdom; and Maasvlakte in Rotterdam, the Netherlands.

SAex is a proposed submarine communications cable linking South Africa to the United States with branches to Namibia, Saint Helena, and Brazil.
The Blue-Raman cable system is a proposed intercontinental fibre-optic communications cable system that will connect France to India via Italy, Greece, Israel, Jordan, Saudi Arabia, Djibouti, and Oman. It is notable in that it avoids passing through Egypt, a country which is widely regarded as a chokepoint for Internet connectivity. Google is a major investor in the system.
