Optical fiber - Wikipedia
网页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 Optics: Understanding the Basics - Photonics
网页Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a medium for conveying information in the form of light pulses, typically in the realm of telecommunications, networking, and data transmission.
Fiber optics | Definition, Inventors, & Facts | Britannica
网页2024年9月5日 · Fiber optics, the science of transmitting data, voice, and images by the passage of light through thin, transparent fibers. In telecommunications, fiber optic technology is used to link computers within local area networks. Fiber optics is also the basis of the fiberscopes used in examining internal parts of the body.
Fiber Optic Basics | Optical Fiber 101 - Corning
网页Optical fiber is a highly-transparent strand of glass that transmits light signals with low attenuation (loss of signal power) over long distances, providing nearly limitless bandwidth. This optical fiber technology enables telecommunications service providers to send voice, data, and video at ever increasing rates.
