Enderby's Wharf
Enderby's Wharf is a wharf and industrial site on the south bank of the Thames in Greenwich, London, associated with Telcon and other companies. It has a history of more than 150 years of production of submarine communication cables and associated equipment, and is one of the most important sites in the history of submarine communications. Location The wharf lies on the Greenwich Peninsula, a little to the north of the historic centre of Greenwich. It is between the Thames and the Blackwall Tunnel approach road, across the river from Cubitt Town. It covers an area of some and has a frontage of around . History The wharf was first developed commercially by the whaling company of Samuel Enderby & Sons. The site was first acquired by Samuel Enderby II, with Morden College assisting in the acquisition of the naval ammunition wharf. It was Samuel Enderby III who initially developed the site along with brothers Charles and George, who acquired the site for a ropeworks. Enderbys al ...

Alexandria
Alexandria ( or ; ar, ٱلْإِسْكَنْدَرِيَّةُ ; grc-gre, Αλεξάνδρεια, Alexándria) is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. During the Hellenistic period, it was home to the Lighthouse of Alexandria, which ranked among the Seven Wonders of the Ancient World, as well as the storied Library of Alexandria. Today, the library is reincarnated in the disc-shaped, ultramodern Bibliotheca Alexandrina. Its 15th-century seafront Qaitbay Citadel is now a museum. Called the "Bride of the Mediterranean" by locals, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez. The city extends about along the northern coast of Egypt, and is the largest city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucent
Lucent Technologies, Inc. was an American multinational telecommunications equipment company headquartered in Murray Hill, New Jersey. It was established on September 30, 1996, through the divestiture of the former AT&T Technologies business unit of AT&T Corporation, which included Western Electric and Bell Labs. Lucent was merged with Alcatel SA of France on December 1, 2006, forming Alcatel-Lucent. Alcatel-Lucent was absorbed by Nokia in January 2016. Name Lucent means "light-bearing" in Latin. The name was applied for in 1996 at the time of the split from AT&T. The name was widely criticised, as the logo was to be, both internally and externally. Corporate communications and business cards included the strapline 'Bell Labs Innovations' in a bid to retain the prestige of the internationally famous research lab, within a new business under an as-yet unknown name. This same linguistic root also gives Lucifer, "the light bearer" (from lux, 'light', and ferre, 'to bear'), w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Optical Amplifier
An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. They are used as optical repeaters in the long distance fiberoptic cables which carry much of the world's telecommunication links. There are several different physical mechanisms that can be used to amplify a light signal, which correspond to the major types of optical amplifiers. In doped fiber amplifiers and bulk lasers, stimulated emission in the amplifier's gain medium causes amplification of incoming light. In semiconductor optical amplifiers (SOAs), electron- hole recombination occurs. In Raman amplifiers, Raman scattering of incoming light with phonons in the lattice of the gain medium produces photons coherent with the inco ...

Optical Communications Repeater
An optical communications repeater is used in a fiber-optic communications system to regenerate an optical signal. Such repeaters are used to extend the reach of optical communications links by overcoming loss due to attenuation of the optical fiber. Some repeaters also correct for distortion of the optical signal by converting it to an electrical signal, processing that electrical signal and then retransmitting an optical signal. Such repeaters are known as optical-electrical-optical (OEO) due to the conversion of the signal. These repeaters are also called regenerators for the same reason. Classification of regenerators Optical regenerations are classified into 3 categories by the 3 R's scheme. # R : reamplification of the data pulse alone is carried out. # 2R : in addition to reamplification, pulse reshaping is carried out. E.g.: Mamyshev 2R regenerator. # 3R : in addition to reamplification and reshaping, retiming of data pulse is done. All-optical regenerators An alternat ...

Standard Telephones And Cables
Standard Telephones and Cables Ltd (later STC plc) was a British manufacturer of telephone, telegraph, radio, telecommunications, and related equipment. During its history, STC invented and developed several groundbreaking new technologies including pulse-code modulation (PCM) and optical fibres. The company was founded in 1883 in London as International Western Electric by the Western Electric Company, shortly after Western Electric became the telephone equipment supplier for the American Telephone and Telegraph Company (AT&T) in the United States. In 1925, Western Electric divested itself of all foreign operations and sold International Western Electric to International Telephone and Telegraph (ITT), in part to thwart antitrust actions by the American government. In mid-1982, STC became an independent company and was listed on the London Stock Exchange; for a time it was a constituent of the FTSE 100 Index. It was bought by Nortel in 1991.

British Insulated Callender's Cables
British Insulated Callender's Cables (BICC) was a 20th-century British cable manufacturer and construction company, now renamed after its former subsidiary Balfour Beatty. It was formed from the merger of two long established cable firms, Callender's Cable & Construction Company and British Insulated Cables. History Callender's Cable & Construction Company Callender's Cable & Construction Company was founded by William Ormiston Callender in 1870. It was originally an importer and refiner of bitumen for road construction but began manufacturing insulated cables at their Erith site on the Thames in the 1880s. It played a significant role in construction of the British National Grid in the 1930s building the 132 kV crossing of the Thames at Dagenham with overhead cables spanning 3060 feet (932m) between two 487 ft (148m) towers, and allowing 250 ft (76m) clearance for shipping. Callender's research and engineering laboratories were based at a former power station site i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Pluto
Operation Pluto (Pipeline Under the Ocean or Pipeline Underwater Transportation of Oil, also written Operation PLUTO) was an operation by British engineers, oil companies and the British Armed Forces to construct submarine oil pipelines under the English Channel in support of Operation Overlord, the Allied invasion of Normandy during the Second World War. The British War Office estimated that petrol, oil and lubricants (POL) would account for 60 per cent or more by weight of the supplies required by the expeditionary forces. Pipelines would reduce the reliance on coastal tankers, which could be affected by bad weather, were subject to air attack, and needed to be offloaded into vulnerable storage tanks ashore. A special kind of pipeline was required. Two types were developed: Hais and Hamel. Hais arose from a proposal originated by Clifford Hartley, the chief engineer with the Anglo-Iranian Oil Company, for a flexible pipe with a lead core that could be laid by a cable- ...

SS Great Eastern
SS ''Great Eastern'' was an iron sail-powered, paddle wheel and screw-propelled steamship designed by Isambard Kingdom Brunel, and built by John Scott Russell & Co. at Millwall Iron Works on the River Thames, London. She was the largest ship ever built at the time of her 1858 launch, and had the capacity to carry 4,000 passengers from England to Australia without refuelling. Her length of was surpassed only in 1899 by the 17,274-gross-ton , her gross tonnage of 18,915 was only surpassed in 1901 by the 20,904-gross-ton and her 4,000-passenger capacity was surpassed in 1913 by the 4,234-passenger . The ship having five funnels (which were later reduced to four) was unusual for the time. The vessel also had the largest set of paddle wheels. Brunel knew her affectionately as the "Great Babe". He died in 1859 shortly after her maiden voyage, during which she was damaged by an explosion. After repairs, she plied for several years as a passenger liner between Britain and North Am ...
