تعريف optik elyaf في التركية الإنجليزية القاموس.

optical fiber

Alternative form of optical fibre

(general optics) Optical fibers provide the transportation of optical signals or/and optical power over a certain distance Most fibers for telecommunication purpose are made of quartz, due to the low losses of downto 0 1dB/km, while some short-distance fibers have cheap and easy to handle plasics as basic material In every case, the guidance of light is provided by total reflection inside the fiber core, wich has a slighly higher refractive index than the rest of the fiber(cladding) An outer plastic coating protects the fiber from mechanical or chemical influences Standard telecommunication fibers have an outer cladding diameter of 0 125mm and core diameters of 9 microns (9/125 monomode fiber) or 50 microns (50/125 multimode fiber) For long distance telecommunications only monomode fibers are used, due to the absence of modal dispersion Sources to get more info

An extremely thin, flexible thread of pure glass, able to carry one thousand times the information possible with traditional copper wire

Optical fiber cables consist of thin filaments of glass (or other transparent materials), which can carry beams of light A laser transmitter encodes frequency signals into pulses of light and sends them down the optical fiber to a receiver, which translates the light signals back into frequencies Less susceptible to noise and interference than other kinds of cables, optical fibers can transmit data greater distances without amplification But because the glass filaments are fragile, optical fiber must be run underground rather than overhead on telephone poles

  A filament of transparent dielectric material, usually glass or plastic, and usually circular in cross section, that guides light (188)  Note 1: An optical fiber usually has a cylindrical core surrounded by, and in intimate contact with, a cladding of similar geometry   Note 2: The refractive index of the core must be slightly higher than that of the cladding for the light to be guided by the fiber   Synonym lightguide

a very thin fiber made of glass that functions as a waveguide for light; used in bundles to transmit images

A flexible optically transparent fiber, usually made of glass or plastic, through which light can be transmitted by successive internal reflections

Filament of quartz of other optical material capable of transmitting light along its conformation and emitting it at the end

Optical fiber (or "fiber optic") is a transmission medium associated with the transmission of information as light pulses along a glass or plastic wire or fiber Optical fiber carries a lot more information than copper wire and is usually not subject to electromagnetic interference and the need to retransmit signals Most of Verizon's inter-office telephone lines are now of optical fiber

A glass or plastic fiber that has the ability to guide light along its axis The three parts of an optical fiber are the core, the cladding, and the coating or buffer

A thin filament of glass Optical waveguide consisting of cladding and a core capable of carrying information in the form of light

A glass conduit that transmits data encoded in light signals

Glass fiber cable used to carry signals made up of lightwaves

See: Fiber-Optic Cable

Any filament of fiber, made of dielectric material, that guides light

A transparent fiber, usually of glass or plastic, that can transmit light down its length by means of total internal reflection

Medium that carries digital data signals in the form of modulated pulses of light An optical fiber consists of an extremely thin cylinder of glass, called the core, surrounded by a concentric layer of glass, known as the cladding

Long strands of glass, thinner than a human hair, which propagate a lightwave signal for use in broadband communications Synonym for fiber, lightguide

Filament of quartz or other optical material capable of transmitting light along its conformation and emitting it at the end

A glass or plastic fiber surrounded by a material with a lower index of refraction Optical fibers transmit light from one end to the other by internal reflection
