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.
Narinder Singh Kapany (31 October 1926 – 4 December 2020) was an Indian-American physicist famously known as "Father of Fiber Optics" . [2] [3] [4] Kapany is a pioneer in the field of fiber optics, known for coining and popularising the term. [5] [6] Fortune named him one of seven "Unsung Heroes of the 20th Century" for his Nobel Prize ...
A bundle of optical fibers A TOSLINK fiber optic audio cable with red light shone in one end. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other.
A formative failure. But it hasn’t all been smooth sailing for the 6-foot-7, 65-year-old Corning CEO. In the 1990s, Weeks was the Corning vice president tapped to run a new optical fiber ...
^ e: OFC/NFOEC – Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference [132] ^ a: Kao's major task was to investigate light-loss properties in materials of optic fibers, and determine whether they could be removed or not. Hockham's was investigating light-loss due to discontinuities and curvature of ...
Robert D. Maurer (born July 20, 1924) is an American industrial physicist noted for his leadership in the invention of optical fiber. In 1979, Maurer was elected a member of the National Academy of Engineering for contributions to the technology of low-loss fibers for optical communication.
World map showing submarine cables in 2015. In the 1980s, fiber-optic cables were developed. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into operation in 1988. A fiber-optic cable comprises multiple pairs of fibers. Each pair has one fiber in each direction. TAT-8 had two operational pairs and one backup ...
Optical fiber with attenuation low enough for communication purposes (about 20 dB/km) was developed in 1970 by Corning Glass Works. At the same time, GaAs semiconductor lasers were developed that were compact and therefore suitable for transmitting light through fiber optic cables for long distances.
