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 acquired by Alcatel SA on December 1, 2006, forming Alcatel-Lucent. 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'), who is also a character in Dante's epic poem ''Inferno''. Shor ...

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 fiber-optic 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 th ...

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 alter ...

Standard Telephones And Cables
Standard Telephones and Cables Ltd (later STC public limited company, 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 Western Electric, the Western Electric Company, shortly after Western Electric became the telephone equipment supplier for AT&T, 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 ...

British Insulated Callender's Cables
British Insulated Callender's Cables (BICC) was a major British cable manufacturer and construction company of the 20th century. It has been renamed after its former subsidiary Balfour Beatty. BICC was created via the merger of two long established cable firms, ''Callender's Cable & Construction Company'' and ''British Insulated Cables'', in 1945. It promptly set about expanding both its product lines and international presence; the latter was augmented by a series of acquisitions, which included the British businesses Pyrotenax Ltd, Power Securities, and Balfour Beatty, along with a variety of interests in Portugal, Spain, East Germany and Russia. During the late 1970s, BICC employed roughly 10,800 staff in manufacturing roles alone; overseas activities had come to comprise roughly half of all turnover generated by this time. Manufacturing sites included Erith, Prescot, Kirkby, Leyton, Helsby, Leigh, Melling, Wrexham, Blackley, Belfast and Huyton. During the 1980s, the compa ...

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 build oil Pipeline transport, pipelines under the English Channel to support Operation Overlord, the Allied invasion of Normandy during the Second World War. The British War Office estimated that petrol, oil, and lubricants would account for more than 60 per cent of the weight of supplies required by the expeditionary forces. Pipelines would reduce the need for coastal tankers, which could be hindered by bad weather, were subject to air attack, and needed to be offloaded into vulnerable storage tanks ashore. A new kind of pipeline was required that could be rapidly deployed. Two types were developed, named "Hais" and "Hamel" after their inventors. Two pipeline systems were laid, each connected by camouflaged pumping stations to the CLH Pipeline System, Avonmouth-Thames pipeli ...

SS Great Eastern
SS ''Great Eastern'' was an iron-hull (watercraft), hulled steamship designed by Isambard Kingdom Brunel, and built by John Scott Russell & Co. at Millwall Iron Works on the River Thames, London, England. Powered by both sidewheels and a screw propeller, she was by far 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 register tonnage, gross tonnage of 18,915 was surpassed only in 1901, by the 20,904-gross-ton and her 4,000-passenger capacity was surpassed only in 1913, by the 4,234-passenger . Her five Funnel (ship), funnels (later reduced to four) was unusual for the time. She also had the largest set of paddle wheels in existence. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
