FALCON (cable System)
Fibre-optic Link Around the Globe (FLAG) is a optical fibre, 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. The Europe-Asia segment was laid by Cable & Wireless Marine in the mid-1990s, and was the subject of an article in ''Wired (magazine), Wired'' magazine in December 1996 by Neal Stephenson. Description The FLAG cable system was first placed into commercial service in late 1997. FLAG offered a speed of 10 Gbit/s, and uses synchronous digital hierarchy technology. It carries over 120,000 voice channels via of mostly undersea cable. FLAG uses erbium-doped fibre amplifiers, and was jointly supplied by AT&T Submarine Systems and KDD-Submarine Cable Systems.

Telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Málaga (province)
Málaga (, ) is a municipality of Spain, capital of the Province of Málaga, in the autonomous community of Andalusia. With a population of 578,460 in 2020, it is the second-most populous city in Andalusia after Seville and the sixth most populous in Spain. It lies on the Costa del Sol (''Coast of the Sun'') of the Mediterranean, about east of the Strait of Gibraltar and about north of Africa. Málaga's history spans about 2,800 years, making it one of the oldest cities in Europe and one of the oldest continuously inhabited cities in the world. According to most scholars, it was founded about 770BC by the Phoenicians as ''Malaka'' ( xpu, 𐤌𐤋𐤊𐤀, ). From the 6th centuryBC the city was under the hegemony of Ancient Carthage, and from 218BC, it was ruled by the Roman Republic and then empire as ''Malaca'' (Latin). After the fall of the empire and the end of Visigothic rule, it was under Islamic rule as ''Mālaqah'' ( ar, مالقة) for 800 years, but in 1487, the C ...

Cornwall
Cornwall (; kw, Kernow ) is a historic county and ceremonial county in South West England. It is recognised as one of the Celtic nations, and is the homeland of the Cornish people. Cornwall is bordered to the north and west by the Atlantic Ocean, to the south by the English Channel, and to the east by the county of Devon, with the River Tamar forming the border between them. Cornwall forms the westernmost part of the South West Peninsula of the island of Great Britain. The southwesternmost point is Land's End and the southernmost Lizard Point. Cornwall has a population of and an area of . The county has been administered since 2009 by the unitary authority, Cornwall Council. The ceremonial county of Cornwall also includes the Isles of Scilly, which are administered separately. The administrative centre of Cornwall is Truro, its only city.

Skewjack
Skewjack is the name of a plot of land in west Cornwall, England, United Kingdom. It is situated about 1.5 miles (2 km) east of Land's End on the B3315 road. It was the site of RAF Sennen, and is now the site of a Fibre-optic Link Around the Globe building. RAF Sennen Skewjack became well known in the Second World War when a Royal Air Force station known as RAF Sennen was set up in 1942 between Skewjack Farm and nearby Trebehor Farm, about half-a-mile (1 km) to the south east. The RAF radar site was actually about 1 mile (1.5 km) from Sennen Churchtown village or about 2 miles (3 km) from Sennen Cove and at a good location for radio line-of-sight (LOS) towards the Atlantic Ocean. Several masts were erected, some over 300 feet (100 m) high, in nearby fields to support radar antennas as part of an early warning radar station. Code-named " Chain Home Low", the equipment was very advanced for the early days of radar, being able to detect ships and approachin ...

FLAG FEA Map
A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the maritime environment, where semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin , meaning "flag" or "banner". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes. Some military units are called "flags" after their use of flags. A ''flag'' (Arabic: ) is equivalent to a brigad ...

Cable Landing Point
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 (in the case of a point-to-point cable system) or via a branch from a main cable using a submarine branching unit. The branch can be several kilometres long. Selection criteria Cable landing points are usually carefully chosen to be in areas: # that have little marine traffic to minimise the risk of cables being damaged by ship anchors and trawler operations; # with gently sloping, sandy or silty sea-floors so that the cable can be buried to minimise the chance of damage; # without strong currents that would uncover buried cables and potentially move cables. Such locations are rare, and will usually be the shared landfall point for several cable systems. Associated facilities Frequently, there will be a nearby cable landing ...

Forward Error Correction
In computing, telecommunication, information theory, and coding theory, an error correction code, sometimes error correcting code, (ECC) is used for controlling errors in data over unreliable or noisy communication channels. The central idea is the sender encodes the message with redundant information in the form of an ECC. The redundancy allows the receiver to detect a limited number of errors that may occur anywhere in the message, and often to correct these errors without retransmission. The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. ECC contrasts with error detection in that errors that are encountered can be corrected, not simply detected. The advantage is that a system using ECC does not require a reverse channel to request retransmission of data when an error occurs. The downside is that there is a fixed overhead that is added to the message, thereby requiring a h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
