MedNautilus (cable System)
MedNautilus is a submarine telecommunications cable system linking countries bordering the Eastern/Central Mediterranean Sea. It is a successor of the LEV system linking Cyprus, Israel and Italy. It has landing points in: # Catania, Sicily, Italy #Chania, Crete, Greece # Koropi (Athens), Greece #Istanbul, Turkey #Tel Aviv, Israel #Haifa, Israel #Pentaskhinos, Cyprus The system comprises 5,729 km of cable. Its total design transmission capacity is 3.84 Tb/ s on 6 fiber pairs. All the landing points except those in Turkey and Cyprus are served by a cable ring which ensures uninterrupted service in case any single segment in the ring fails or has its cable severed. Telecom Italia, which owns the MedNautilus and LEV systems held a virtual monopoly on international cable-based communications to and from Israel. This is changed in 2012 however, with Bezeq International completing a 12.8Tbit/s submarine fiber optic cable to Italy and Tamares Telecom laying a 42Tbit/s submari ...

Catania
Catania (, , Sicilian and ) is the second largest municipality in Sicily, after Palermo. Despite its reputation as the second city of the island, Catania is the largest Sicilian conurbation, among the largest in Italy, as evidenced also by the presence of important road and rail transport infrastructures as well as by the main airport in Sicily, fifth in Italy. It is located on Sicily's east coast, at the base of the active volcano, Mount Etna, and it faces the Ionian Sea. It is the capital of the 58-municipality region known as the Metropolitan City of Catania, which is the seventh-largest metropolitan city in Italy. The population of the city proper is 311,584, while the population of the Metropolitan City of Catania is 1,107,702. Catania was founded in the 8th century BC by Chalcidian Greeks. The city has weathered multiple geologic catastrophes: it was almost completely destroyed by a catastrophic earthquake in 1169. A major eruption and lava flow from nearby Mount ...

Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submarine Communications Cables In The Mediterranean Sea
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 ...

Bezeq International
Bezeq ( he, בזק) is an Israeli telecommunications company. Bezeq and its subsidiaries offer a range of telecom services, including fixed-line, mobile telephony, high-speed Internet, transmission, and pay TV (via Yes). History Bezeq was founded in 1984 as a government-owned corporation, taking over the provision of telephony services in Israel, which had been run directly by the Ministry of Communications. The previous system was highly bureaucratic, requiring customers to wait lengthy periods of time for a telephone line. In the late 1980s Anat Hoffman founded a group to protect the interests of Bezeq customers. A major complaint was that Bezeq did not send customers itemized bills. 46 cases were brought to small claims court and the consumers won 43 of them. Within two years of the campaign. consumers began to receive itemized bills. In 1994, Bezeq acquired 50% ownership of Pelephone, Israel's first mobile communication company, in 2004 acquired full ownership of the com ...

Telecom Italia
Gruppo TIM, legally TIM S.p.A. (formerly Telecom Italia S.p.A.), also known as the TIM Group in English, is an Italian telecommunications company with headquarters in Rome, Milan, and Naples, (with the Telecom Italia Tower) which provides fixed telephony and DSL data services. It is the largest Italian telecommunications services provider in revenues and subscribers. It was founded in 1994 by the merger of several state-owned telecommunications companies, the most prominent of which was Società Italiana per l'Esercizio Telefonico p.A., (known as ''SIP''), the former state monopoly telephone operator in Italy. The company's stock is traded in the Borsa Italiana. Since 2017, the Italian State exercises on TIM the "Golden Power", which allows the government to take a number of actions when the strategic interests of the country are concerned.

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 ...
