Tonga Cable System
Tonga Cable System is a submarine fiber-optic cable system connecting Tonga with Fiji, where it connects to other international networks. It is long and was activated in 2013. It has cable landing points at Sopu, a suburb of Nukuʻalofa in Tonga, and Suva, Fiji. The project was funded by Asian Development Bank and the World Bank. An extension of the cable to Haʻapai and Vavaʻu Vavau is an island group, consisting of one large island (ʻUtu Vavaʻu) and 40 smaller ones, in Tonga. It is part of Administrative divisions of Tonga, Vavaʻu District, which includes several other individual islands. According to tradition, ... was commissioned in April 2018. History On 20 January 2019, the cable broke and disrupted Internet services to Tonga. Satellite communications were used as a backup. Three years later, the 2022 Hunga Tonga–Hunga Ha'apai eruption disrupted it again. A specialist repair ship from SubCom could take days to get to the fault site, as it was deployed from ...

Submarine Communications Cable
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 were laid beginning in the 1850s and 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 cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Territory, Australia, in 1871 in anticipation of the completion of the Australian Overland Telegraph Line in 1872 connecting to Adelaide, South Australia and thence to the rest of Australia. Subsequent generations of cables carried telephone traffic, then data transmission, data communications traffic. These early cables used copper wires in their cores, but modern cables use optical fiber technology to carry digital data, whic ...

Fiber-optic Cable
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for fiber-optic communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building. Design Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or ...

Tonga
Tonga, officially the Kingdom of Tonga, is an island country in Polynesia, part of Oceania. The country has 171 islands, of which 45 are inhabited. Its total surface area is about , scattered over in the southern Pacific Ocean. according to Johnson's Tribune, Tonga has a population of 104,494, 70% of whom reside on the main island, Tongatapu. The country stretches approximately north-south. It is surrounded by Fiji and Wallis and Futuna (France) to the northwest, Samoa to the northeast, New Caledonia (France) and Vanuatu to the west, Niue (the nearest foreign territory) to the east and Kermadec (New Zealand) to the southwest. Tonga is about from New Zealand's North Island. Tonga was first inhabited roughly 2,500 years ago by the Lapita civilization, Polynesian settlers who gradually evolved a distinct and strong ethnic identity, language, and culture as the Tongan people. They quickly established a powerful footing across the South Pacific, and this period of Tong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fiji
Fiji, officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about . The most outlying island group is Ono-i-Lau. About 87% of the total population live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts, either in the capital city of Suva, or in smaller urban centres such as Nadi (where tourism is the major local industry) or Lautoka (where the Sugarcane, sugar-cane industry is dominant). The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geothermal activity still occurs today on the islands of Vanua Levu and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cable Landing Point
A cable landing point is the location where a Submarine cable, submarine or other underwater cable makes landfall. The term is most often used for the landfall points of submarine communications cable, 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 Fr ...

Nukuʻalofa
Nukualofa ( , ) is the Capital city, capital and largest city of Tonga. It is located on the north coast of the island of Tongatapu, in the country's southernmost island group. History First western records of Nukualofa On 10 June 1777, British captain James Cook wrote of his arrival at their anchorage place. His description of the place confirmed, with his map, that this was the bay of Nukualofa. Cook never used the name Nukualofa or any alternative spelling for the reports of this voyage, but he mentioned the island of Pangaimodoo (Pangaimotu (Tongatapu), Pangaimotu) which was to the east of his anchorage position. Captain Cook also wrote that he travelled by canoes to visit Mooa (Muʻa (Tongatapu), Mua) where Paulaho and other great men lived. The house that Paulaho provided was on the beach from the ship. Reference to his map shows that he must have landed and stayed in the Siesia area, the eastern part of modern Nukualofa. Cook also drafted the first map of the bay of Nu ...

Suva
Suva (, ) is the Capital city, capital and the most populous city of Fiji. It is the home of the country's largest metropolitan area and serves as its major port. The city is located on the southeast coast of the island of Viti Levu, in Rewa Province, Central Division, Fiji, Central Division. In 1877, the capital of Fiji was moved to Suva from Levuka, the main European colonial settlement at the time, due to the restrictive geography and environs of the latter. The administration of the colony was transferred from Levuka to Suva in 1882. As of the 2017 census, the city of Suva had a Demographics of Fiji, population of 93,970, and Suva's metropolitan area, which includes its independent suburbs, had a population of 185,913. The combined urban population of Suva and the towns of Lami, Fiji, Lami, Nasinu, and Nausori that border it was around 330,000: over a third of the nation's population (This urban complex, excluding Lami, is also known as the Suva-Nausori corridor).
