Fiber to the x — (FTTX) is a generic term for any network architecture that uses optical fiber to replace all or part of the usual copper local loop used for telecommunications. The four technologies, in order of an increasingly longer fiber loop are:* Fiber to… … Wikipedia
Fiber tapping — is a method to extract signal from an optical fiber without breaking the connection. Tapping of optical fiber allows diverting some of the signal being transmitted in the core of the fiber into another fiber or a detector. Fiber to the home… … Wikipedia
Signal reflection — occurs when a signal is transmitted along a transmission medium, such as a copper cable or an optical fiber, some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This… … Wikipedia
Signal lamp — training during World War II. A signal lamp (sometimes called an Aldis lamp, named after Arthur C. W. Aldis who invented a widely used design) is a visual signaling device for optical communication (typically using Morse code). Modern signal… … Wikipedia
Fiber optics — Fi ber op tics,, n. that branch of optics which studies the transmission of light through thin transparent fibers. Note: Light transmission through optical fibers has become an important means of data and telephone signal transmission, in some… … The Collaborative International Dictionary of English
Fiber To The Home — Installation de la fibre optique chez un particulier FTTH est l abréviation du terme anglais Fiber To The Home, signifiant littéralement en français « fibre jusqu au foyer » encore appelée, en français, fibre optique à domicile. Il s… … Wikipédia en Français
Fiber-optic communication — An optical fiber junction box. The yellow cables are single mode fibers; the orange and blue cables are multi mode fibers: 50/125 µm OM2 and 50/125 µm OM3 fibers respectively. Fiber optic communication is a method of transmitting information from … Wikipedia
Fiber laser — A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers,… … Wikipedia
Fiber Bragg grating — A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the… … Wikipedia
Fiber optic sensor — A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ( intrinsic sensors ), or as a means of relaying signals from a remote sensor to the electronics that process the signals ( extrinsic sensors ). Fibers have… … Wikipedia
fiber-optic cable — A transmission technology that sends pulses of light along specially manufactured optical fibers. Each fiber consists of a core, thinner than a human hair, surrounded by a sheath with a much lower refractive index. Light signals introduced… … Dictionary of networking
