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.
Transatlantic telegraph cables were undersea cables running under the Atlantic Ocean for telegraph communications. Telegraphy is now an obsolete form of communication, and the cables have long since been decommissioned, but telephone and data are still carried on other transatlantic telecommunications cables. The first cable was laid in the 1850s from Valentia Island off the west coast of Ireland to Bay of Bulls, Trinity Bay, Newfoundland. The first communications occurred on August 16th 1858, but the line speed was poor, and efforts to improve it caused the cable to fail after three weeks.
Gutta-percha is a tree of the genus Palaquium in the family Sapotaceae. The name also refers to the rigid, naturally biologically inert, resilient, electrically nonconductive, thermoplastic latex derived from the tree, particularly from Palaquium gutta; it is a polymer of isoprene which forms a rubber-like elastomer.
Commercial Pacific Cable Company was founded in 1901, and ceased operations in October 1951. It provided the first direct telegraph route from America to the Philippines, China, and Japan.
Charles Mitchell was a Scottish engineer from Aberdeen who founded major shipbuilding yards on the Tyne. He became a public benefactor who funded notable buildings that still survive today.
The All Red Line was a system of electrical telegraphs that linked much of the British Empire. It was inaugurated on 31 October 1902. The informal name derives from the common practice of colouring the territory of the British Empire red or pink on political maps.
A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, for electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves for guiding cable over bow or stern or both. Bow sheaves, some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, as seen in the photo of CS Cable Innovator at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS Long Lines.
Sir Charles Tilston Bright was a British electrical engineer who oversaw the laying of the first transatlantic telegraph cable in 1858, for which work he was knighted.
The Hooper's Telegraph Works Ltd was established by William Hooper in 1870 to manufacture and lay submarine communications cable using his patented vulcanized rubber core. Before the company was formed to produce finished submarine cable Hooper had furnished core for other companies, particularly that of William Thomas Henley, to armor and sheathe. The original core works were located at Mitcham, London with the later complete cable, core with external sheathing, production located and later consolidated at Millwall and the company renamed Hooper's Telegraph Works.
Willoughby Smith was an English electrical engineer who discovered the photoconductivity of the element selenium. This discovery led to the invention of photoelectric cells, including those used in the earliest television systems.
William Thomas Henley (1814–1882) was a pioneer in the manufacture of telegraph cables. He was working as a porter in Cheapside in 1830, leaving after disputes with his employer, and working at the St Katherine Docks for six years. During those years he was determined to learn a trade and used money from an aunt to purchase a lathe, vice and lumber with which he made a work bench. With those tools he taught himself to turn wood and brass and began to experiment, including with electricity.
William Hooper was a British chemist.
Penfold Golf Ltd. is a British sporting goods manufacturer of golf equipment founded in 1929 by Albert Ernest Penfold (1884–1941). Golf equipment include balls, tees, gloves, apart from fashion accessories such as hats and wallets.
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.
Sir Samuel Canning (1823–1908) was an English pioneer of submarine telegraphy.
The Submarine Telegraph Company was a British company which laid and operated submarine telegraph cables.
The Gutta Percha Company was an English company formed in 1845 to make a variety of products from the recently introduced natural rubber gutta-percha. Unlike other natural rubbers, this material was thermoplastic allowing it to be easily moulded. Nothing else like it was available to manufacturing until well into the twentieth century when synthetic plastics were developed.
The British and Irish Magnetic Telegraph Company was founded by John Brett in 1850. The Magnetic was the principal competitor to the largest telegraph company in the United Kingdom, the Electric Telegraph Company. The Magnetic was the leading company in Ireland, while the Electric was the leading company in mainland Britain. Between them, they dominated the market until the telegraph was nationalised in 1870.
Hugh Adams Silver was an English businessman, civil engineer and military officer.
In the nineteenth century, the United Kingdom of Great Britain and Ireland had the world's first commercial telegraph company. British telegraphy dominated international telecommunications well into the twentieth. Telegraphy is the sending of textual messages by human operators using symbolic codes. Electrical telegraphy used conducting wires to send messages, often incorporating a telegram service to deliver the telegraphed communication from the telegraph office. This is distinct from optical telegraphy that preceded it and the radiotelegraphy that followed. Though Francis Ronalds first demonstrated a working telegraph over a substantial distance in 1816, he was unable to put it into practical use. Starting in 1836, William Fothergill Cooke, with the scientific assistance of Charles Wheatstone, developed the Cooke and Wheatstone telegraph. The needle telegraph instrument suggested by Wheatstone, the battery invented by John Frederic Daniell, and the relay invented by Edward Davy were important components of this system.
