English

Subject field(s)
  • Optical Telecommunications
CONT

Fiber optics depend on pulses of light, transmitted through fine transparent fibers, rather than on pulses of electric current sent through conducting wires. The purpose is to transmit information rather than power. By proper modulation of the light signals, a very wide information bandwidth can be achieved, and because the fibers can be made thin, a large bundle can be accommodated in a single cable of comparatively small diameter. The signals are not vulnerable to eavesdropping, nor are they susceptible to jamming or to transmission of damaging currents due to an electromagnetic pulse from a nuclear explosion. Fiber optics are replacing electric wires for many applications, including computer links.

Record 3 2002-09-17

English

Subject field(s)
  • Radiotelephony
  • Telecommunications Facilities
DEF

A transmission system utilizing hair-thin glass fibres through which light is transmitted. Information is transferred by modulating the transmitted light.

OBS

These modulated signals are detected by light-sensitive semiconductor devices. The signals are regenerated to relay the information and demodulated to retrieve the information.

Key term(s)
  • fiber optics
  • fibre optic
  • fiber optic

French

Domaine(s)
  • Radiotéléphonie
  • Installations de télécommunications
DEF

Moyen de transmission faisant appel à des fibres de verre, minces comme des cheveux, à travers lesquelles la lumière est transmise.

OBS

L'information est acheminée par modulation de la lumière ainsi véhiculée. Ces signaux modulés sont captés par des détecteurs photosensibles. Ils sont ensuite reconstitués pour la retransmission, puis démodulés à leur arrivée.

Spanish

Campo(s) temático(s)
  • Radiotelefonía
  • Instalaciones de telecomunicaciones
DEF

Filamento o grupo de filamentos fabricados con fibras de vidrio de gran pureza por cuyo núcleo se pueden transmitir señales de luz generadas por un láser o por diodos emisores de luz (LED) y que se utilizan como medio de transmisión en telecomunicaciones.
