Southern Cross Cable
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 of submarine and 1,600 km of terrestrial fiber optic cables, all which operate in a triple-ring configuration. Initially, each cable had a bandwidth capacity of 120 gigabit/s. In April 2008 this capacity was doubled, and was once again upgraded to 860 gigabit/s at the end of 2008. Southern Cross upgraded the existing system to 1.2 Tbit/s in May 2010. After successful trials of 40G technology the first 400G of a planned 800G upgrade has been completed in February 2012, and the remaining 400G was completed in December 2012. An additional 400G was deployed utilizing 100G coherent wavelength technology in July 2013, taking total system capacity to 2.6Tbit/s, with an additional 500Gbit/s to be deployed per segment by Q2 2014, increasing total system capa ...

Telecommunications In Australia
Telecommunications in Australia refers to communication in Australia through electronic means, using devices such as telephone, television, radio or computer, and services such as the telephony and broadband networks. Telecommunications have always been important in Australia given the 'tyranny of distance' with a dispersed population. Governments have driven telecommunication development and have a key role in its regulation. History Colonial period Prior to Federation of Australia in 1901, each of the six Australian colonies had its own telephony communications network. The Australian networks were government assets operating under colonial legislation modelled on that of Britain. The UK Telegraph Act 1868 for example empowered the Postmaster-General to 'acquire, maintain and work electric telegraphs' and foreshadowed the 1870 nationalisation of competing British telegraph companies. Australia's first telephone service (connecting the Melbourne and South Melbourne offi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Narrabeen
Narrabeen is a beachside suburb in northern Sydney, in the state of New South Wales, Australia. Narrabeen is 23 kilometres north-east of the Sydney central business district, in the local government area of Northern Beaches Council and is part of the Northern Beaches region. This area was named Broken Bay by James Cook as he sailed by. History There are a number of theories on the origin of the name "Narrabeen". The most fanciful is that Narrabeen is named after "narrow beans" which the English in the first year of settlement (1788) found and ate from a vine growing over beach sand. Surgeon White indeed recorded getting ill from such beans but this was well north of Narrabeen, near Broken Bay. The name Narrobine Creek appears in 1801 in records relating to two escaped convicts, and thus the name appears to have been in use before then. Another suggestion is that it derives from an Aboriginal word meaning swan. Surveyor James Meehan placed the name Narabang Narabang Lago ...

Australia–France Relations
Diplomatic relations exist between Australia and France, as well as the historical contacts, shared values of democracy and human rights, substantial commercial links, and a keen interest in each other's culture. The two countries maintain diplomatic relations in each other's countries. France is also one of Australia's closest neighbours with less than 700km separating the two countries between New Caledonia and Norfolk Island. Relationship The legacy of Australian involvement on French soil in the First and Second World Wars plays an important role in the bilateral relationship. Over 45,000 Australians lost their lives on French soil in the two conflicts. Each year many Australians travel to the Western Front to commemorate the thousands of Australians who were killed and injured there in World War I. Dialogue and practical cooperation between France and Australia has been strengthening on many fronts in recent years, including on key global security issues such as arm ...

Submarine Communications Cables In The Pacific Ocean
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of spe ...

Bandwidth (computing)
In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth. This definition of ''bandwidth'' is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics, in which ''bandwidth'' is used to refer to analog signal bandwidth measured in hertz, meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power. The actual bit rate that can be achieved depends not only on the signal bandwidth but also on the noise on the channel. Network capacity The term ''bandwidth'' sometimes defines the net bit rate 'peak bit rate', 'information rate,' or physical layer 'useful bit rate', channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system. For example, bandwidth test ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Broadband
In telecommunications, broadband is wide bandwidth data transmission which transports multiple signals at a wide range of frequencies and Internet traffic types, that enables messages to be sent simultaneously, used in fast internet connections. The medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair or satellite. In the context of Internet access, broadband is used to mean any high-speed Internet access that is always on and faster than dial-up access over traditional analog or ISDN PSTN services. Overview Different criteria for "broad" have been applied in different contexts and at different times. Its origin is in physics, acoustics, and radio systems engineering, where it had been used with a meaning similar to "wideband", or in the context of audio noise reduction systems, where it indicated a single-band rather than a multiple-audio-band system design of the compander. Later, with the advent of digital telecommunications, the term was mainly ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cable Landing Station
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 ...

Loyalty Islands
The Loyalty Islands Province ( French ''Province des îles Loyauté'') is one of three administrative subdivisions of New Caledonia encompassing the Loyalty Island (french: Îles Loyauté) archipelago in the Pacific, which are located northeast of the New Caledonian mainland of Grande Terre. The provincial government seat is part of the French territory of New Caledonia, at Lifou, which is away. The Loyalty Islands are a ''collectivité territoriale'' of France. The province's 2019 population was approximately 18,353 inhabitants living on almost . The native inhabitants are the Kanak and the Tavu'avua' peoples. History The first Western contact on record is attributed to British Captain William Raven of the whaler ''Britannia'', who was on his way in 1793 from Norfolk Island to Batavia (now called Jakarta). It is very likely, however, that the discovery and name originated with officials on the London ship ''Loyalty'', which was on a Pacific Ocean trading voyage from 1789 to ...
