An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. [1][2] The light is a form of carrier wave that is modulated to carry information. [3] Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to ...
Charles K. Kao. Sir Charles Kao Kuen (simplified Chinese: 高锟; traditional Chinese: 高錕; pinyin: Gāo Kūn) GBM KBE FRS FREng [5][6][7][8][9] (November 4, 1933 – September 23, 2018) was a Chinese physicist and Nobel laureate who contributed to the development and use of fibre optics in telecommunications.
Fiberscope. A low quality fiberscope observing the inside of an antique clock mechanism. Note how individual fibers are discernable, as each fiber only relays one part of the image. A fiberscope is a flexible optical fiber bundle with a lens on one end and an eyepiece or camera on the other. It is used to examine and inspect small, difficult-to ...
Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices . The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone ...
Narinder Singh Kapany (31 October 1926 – 4 December 2020) was an Indian-American physicist best known for his work on 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-deserving ...
The photophone was a precursor to the fiber-optic communication systems that achieved worldwide popular usage starting in the 1980s. [ 9 ] [ 10 ] [ 11 ] The master patent for the photophone ( U.S. patent 235,199 Apparatus for Signalling and Communicating, called Photophone ) was issued in December 1880, [ 5 ] many decades before its principles ...
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 ...
