fiber optics


An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applie science and engineering concerned with the design and application of optical fibers. Optical fibers are widely used in fiber-optic communication, which permits transmission over longer distances and at higher data rates than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and they are immune to electromagnetic interference. Optical fibers are also used to form sensors, and in a variety of other applications.

Trivia about fiber optics

  • QVC sold out of a Christmas sweater that had reindeer whose noses lit up using this technology with hair-thin filaments
  • This branch of physics came out of the combined work of Bell Labs & Corning Glass
  • Narinder Kapany coined this term for transmission of light through strands of glass
