A tube, generally of glass or plastic, that guides light through its length by using refraction. Optical fibers have the capability of transferring large amounts of information with little loss when the information is contained in characteristics of a beam of light. The photo to the right shows a magnified view of a step-index optical fiber, placed next to a sewing needle. The core and cladding of the fiber have been uncovered, and their diameters indicated, in the photo.

long strands of glass, thinner than a human hair, which propagate a lightwave signal for use in broadband communications.
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.
Dielectric material that guides light; optical waveguide.
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.

Optical fiber (or "fiber optic") refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber.
A very thin strand of transparent glass-like material that can be used to carry light pulses very long distances and at extremely high speeds.
An extremely thin flexible thread of pure cladded glass able to carry millions of times the information of a traditional copper wire, and do it over greater distances.
Fiber made of dielectric material and consisting of the core, light- carrying medium, and the cladding, protective layer allowing total internal reflection of the light for propagation purposes.
Normally a glass (sometimes plastic) waveguide, that transmits light over long distances. The fiber is made of an inner core and surrounding cladding materials. The cladding had an index of refraction higher than that of the core so as to totally reflect the light internally in the fiber. The cladding is coated in a polymer to protect it from damage.
An extremely fine-drawn glass fiber of exceptional purity that will transmit laser light impulses with high fidelity.
A glass conduit that transmits data encoded in light signals.
Filament of transparent dielectric material, usually glass or plastic, and usually circular in cross section, that guides light.
A glass strand conductor designed to conduct light waves modulated with audio or video information. (See also fiber optic.)
Refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber. Optical fiber carries much more information than conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals.
(fiber-optic cable). A tiny (smaller than a hair) cable made of glass and plastic.
Cable made of glass fibers through which signals are transmitted as pulses of light.
A very thin flexible glass or plastic strand along which large quantities of information can be transmitted in the form of light pulses; used in telecommunications, medicine, and other fields. Also called a light guide.
A flexible visually transparent slender object, usually made of glass or plastic, through which light can be transmitted by successive internal reflections.
(fiber optic) Also called fiber-optic cable. A thin, flexible glass or plastic fiber capable of transmitting light over considerable distances by internal reflection.
A thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower index material to promote internal reflection. It may be used singly to transmit pulsed optical signals (communications fiber) or in bundles to transmit light or images.
A transmission medium consisting of a core of glass or plastic surrounded by a protective cladding. Signals are transmitted as light pulses introduced into the fiber by a light transmitter i.e. Laser or an LED.
Thin filaments of glass through which light beams are transmitted. Enormous capacity, low-cost, low-power consumption, small space, lightweight, insensitivity to electromagnetic interference characterize this transport media.
Bundles of transparent glass or plastic strands able to transmit billions of bits of information per second in the form of light pulses generated by lasers. Telephone companies are systematically replacing conventional copper wire (metallic) with these enclosed thin glass wires, vastly increasing the variety and quality of services that can be offered to consumers. In addition to speed, optical systems are not subject to interference from random radiation in the environment as are metallic systems.
An extremely thin, flexible thread of pure glass, able to carry one thousand times the information possible with traditional copper wire.
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.
Thin glass wire designed for light transmission, capable of transmitting billions of bits per second. Unlike electrical pulses, light pulses are not affected by random radiation in the environment.
n. A thin strand of transparent material used to carry optical signals. Optical fibers are constructed from special kinds of glass and plastic, and they are designed so that a beam of light introduced at one end will remain within the fiber, reflecting off the inner surfaces as it travels down the length of the fiber. Optical fibers are inexpensive, compact, and lightweight and are often packaged many hundred to a single cable. See also fiber optics.
Waveguide filament of drawn plastic or glass for the efficient propagation of light. Fibers are comprised of a core surrounded by a relatively thin cladding layer of lower index material. This geometry causes internal reflection of light inside the fiber, and defines the maximum angles accepted by the fiber. Optical fibers emit into a cone of equal angle, not as a beam of light. Coherent fiber bundles can relay images from one end to the other.

An optical fiber (or fibre) is a glass or plastic fiber designed to guide light along its length by total internal reflection. Fiber optics is the branch of applied science and engineering concerned with such optical fibers. Optical fibers are widely used in fiber-optic communication, which permits digital data transmission over longer distances and at higher data rates than other forms of wired and wireless communications.
