Clear All Filters x fibre x
all-silica fiber

Also known as all-glass fiber. A fiber with both a silica core and a silica cladding, regardless of the presence of a polymer overcoat or buffer.

A package for an optical fiber or fibers that may include cladding, buffering, strength members and an outer jacket.

dark fiber

Unused fiber; fiber that has been installed but reserved for future use. Carrying no light.

deeply depressed cladding fiber

An optical fiber, usually a single-mode fiber, that has an outer cladding with nearly the same index of refraction as the core and an inner cladding with a very low index of refraction.

dispersion-flattened single-mode fiber

A type of glass optical fiber that provides low pulse dispersion over a broad portion of the light spectrum and as a result can operate at 1300-nm and 1550-nm wavelengths simultaneously.

dispersion-shifted fiber

A dispersion-shifted fiber (DSF) refers to a type of optical fiber designed to minimize the effects of chromatic dispersion, which is the phenomenon where different wavelengths of light travel at...

double-clad fiber

Double-clad fiber (DCF) is a specialized optical fiber that features two concentric cladding layers surrounding a core. The design of double-clad fibers allows them to be used in various...

double-window fiber

Optical fiber capable of operating at both a shorter and a longer wavelength.

dual-window cable -> double-window fiber

Optical fiber capable of operating at both a shorter and a longer wavelength.

erbium-doped fiber amplifier

An optical fiber that can be used to amplify an optical input. Erbium rare earth ions are added to the fiber core material as a dopant in typical levels of a few hundred parts per million. The fiber...

extrinsic fiber loss

A type of optical fiber loss resulting from the misalignment of fibers in a splice or connector.

faceplate -> fiber optic faceplate

A plate made up of thousands of glass fibers arranged parallel to one another, i.e., in a coherent bundle, and fused together so that it is hermetically tight. It transfers an image from one plane to...

fiber -> optical fiber

Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a...

fiber axis

The mechanical centerline through the core of an optical fiber.

fiber bandwidth

The lowest frequency at which the magnitude of the fiber transfer function decreases to a specified fraction of the zero frequency value. Often, the specified value is one-half the optical power at...

fiber Bragg grating

A fiber Bragg grating (FBG) is a type of optical filter that is inscribed or "written" into the core of an optical fiber. It consists of a periodic modulation of the refractive index along the length...

fiber bundle

A rigid or flexible, concentrated assembly of glass or plastic fibers used to transmit optical images or light. See aligned bundle; incoherent bundle.

fiber curl

A property of optical fiber that results from thermal stresses during manufacturing and is defined as the amount of curvature over any specified length of fiber.

fiber distributed data interface

A standard for fiber optic data transmission systems being developed by the American National Standards Institute (ANSI) and associated working groups that will make fiber optic components from...

fiber fuse

A phenomenon in which high optical power, encountering an imperfection in an optical fiber, destroys the fiber's core and causes damage to back-propagate down the fiber. It is caused by classic...

fiber fusion -> fusion splice

A splice accomplished by the application of localized heat sufficient to fuse or melt the ends of two lengths of optical fiber, forming a continuous single fiber.

fiber lapping

A method of optical fiber coupling in which the fibers are ground down to expose their cores and placed together to allow light pulses to transfer from one to the other.

fiber laser

A fiber laser is a type of laser in which the active gain medium is an optical fiber doped with rare-earth ions such as erbium, ytterbium, or neodymium. Fiber lasers generate coherent light through...

fiber optic cable assembly

A fiber optic cable assembly refers to a complete unit consisting of optical fibers, connectors, protective jackets, and other components that are assembled together to facilitate the transmission of...

fiber optic cable

A package for an optical fiber or fibers that may include cladding, buffering, strength members and an outer jacket.

fiber optic cleaver

A device used to prepare optical fiber end faces; a scribe line made by the cleaver's blade propagates across the fiber, resulting in a clean break.

fiber optic connector -> connector

Hardware installed on fiber cable ends to provide cable attachment to a transmitter, receiver or other cable. Usually a device that can be connected and disconnected repeatedly.

fiber optic coupler -> coupler

1. In color development, the chemical that combines with certain by-products of the development procedure to form a dye. 2. Device for distributing optical power among two or more ports. 3. Device...

fiber optic faceplate

fiber optic field flattener

A plate consisting of fused optical fibers with both surfaces ground and polished, and having the entrance surface curved to match the image curvature of the input lens system. The plate transmits to...

fiber optic guided missile

A weapon launched from a ground-based platform and controlled by a two-way fiber optic data link. The fiber is payed out from a bobbin in the back of the missile.

fiber optic gyroscope

A fiber optic gyroscope (FOG) is a type of gyroscope that uses the interference of light waves to detect changes in orientation or rotation. It operates based on the principle of the Sagnac effect,...

fiber optic illuminators -> fiber optics

The use of thin flexible glass or plastic fibers as wave guides — or "light pipes" — to channel light from one location to another. Fiber optics is based off of the principle of total...

fiber optic lightguide

A bundle of optical fibers arranged randomly for the purpose of transmitting energy, not an image.

fiber optic plate -> fiber optic faceplate

fiber optic probe

A flexible single- or multifiber cable having a bundle of glass fibers arranged to transmit an image.

fiber optic ribbon

A coherent optical fiber bundle in which the configuration is flat rather than round, giving an output in a line.

fiber optic scanner

A scanner in which a fiber optic assembly replaces a lens system.

fiber optic scrambler

A device used for coding messages and having a fiber bundle that is aligned at both ends and scrambled in the middle, potted and cut. The resulting halves of the bundles serve as encoders or decoders...
