Fiber, английский
- General term for any long, narrow cell of wood.
- Волокно, нить
- A single optical transmission element characterized by a core, a cladding, and a coating. two common structures, single-mode (with a step-index profile) or multimode (with a graded-index profile) are used for fiber optic communication systems. different variations are made depending on the attenuation, bandwidth, dispersion, wavelengths, and mechanical requirements
- Us same as fibre
- Волокно
- [1] any substance (such as cotton, flax, or hemp) that can be separated into threads and twisted or braided together (i.e., to make rope). [2] the word has other meanings in anatomy (nerve, muscle, or connective tissue), botany (slender, threadlike root), nutrition (bulk, dietary fiber, roughage), optics (optical fiber), and as a character trait (moral fiber).
- Волокно; фибра о ~ in
- Term for a unit of any natural or synthetic textile raw material used for manufacturing fabric.
- Термин для единицы любого натурального или синтетического текстильного сырья, используемого для производства ткани.
- A unit of matter, either natural or manufactured, that forms the basic element of fabrics and other textile structures. a fiber is characterized by having a length at least 100 times its diameter or width. the term refers to units that can be spun into a yarn or made into a fabric by various methods including weaving, knitting, braiding, felting, and twisting. the essential requirements for fibers to be spun into yarn include a length of at least 5 millimeters, flexibility, cohesiveness, and sufficient strength. other important properties include elasticity, fineness, uniformity, durability, and luster. (also see manufactured fiber and natural fiber.)

Fiber (fibre), английский
- The characteristic of wrought metal that indicates directional properties and is revealed by the etching of a longitudinal section or is manifested by the fibrous or woody appearance of a fracture. it is caused chiefly by the extension of the constituents of the metal, both metallic and nonmetallic, in the direction of working.
- The pattern of preferred orientation of metal crystals after a given deformation process, usually wiredrawing.

Fiber amplifier, английский
- Most common are the erbium doped fiber amplifiers (edfas), semiconductor optical amplifiers (soas), and raman amplifiers, which are used to increase signal gain without electrical conversion
- An optical fiber doped to amplify light from an external source. the most important type is the erbium-doped fiber amplifier.

Fiber architecture, английский
The spatial arrangement of fibers in the preform. each architecture has a definite repeating unit.
Fiber axis, английский
Ось симметрии волокнистой текстуры, продольная ось проволоки
Fiber bandwidth, английский
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 zero frequency.
Fiber bed filter, английский
Fiber bonding (binding), английский
Fiber bragg grating (fbg), английский
- A piece of photo-refractive fiber that is exposed to highintensity uv interference patterns, causing it to reflect a specific wavelength while being transparent to all other wavelengths. used as a filter in wdm systems
- An optical fiber in which the core refractive index varies periodically, causing bragg scatting at wavelengths selected by the period and refractive index. a fiber bragg grating reflects the selected wavelength and transmits others.
Fiber bragg gratings, английский
Reflective structures in the core of an optical fiber with a periodic or aperiodic perturbation of the effective refractive index
Fiber cables, английский
Cables containing one or several optical fibers

Triacetate fiber, английский
A manufactured fiber produced from cellulose triacetate in the forms of filament yarn, staple, and tow. cellulose triacetate fiber differs from acetate fiber in that during its manufacture the cellulose is completely acetylated whereas acetate, which is diacetate, is only partially acetylated. the ftc notes that a fiber may be called triacetate when not less than 92% of the hydroxyl groups are acetylated. fabrics of triacetate have higher heat resistance than acetate fabrics and can be safely ironed at higher temperatures. triacetate fabrics that have been properly heat-set (usually after dyeing) have improved ease-of-care characteristics because of a change in the crystalline structure of the fiber. (also see acetate fiber.)
Acetate fiber, английский
A manufactured fiber in which the fiber-forming substance is cellulose acetate (ftc definition). acetate is manufactured by treating purified cellulose refined from cotton linters and/or wood pulp with acetic anhydride in the presence of a catalyst. the resultant product, cellulose acetate flake, is precipitated, purified, dried, and dissolved in acetone to prepare the spinning solution. after filtration, the highly viscous solution is extruded through spinnerets into a column of warm air in which the acetone is evaporated, leaving solid continuous filaments of cellulose acetate. the evaporated acetone is recovered using a solvent recovery system to prepare additional spinning solution. the cellulose acetate fibers are intermingled and wound onto a bobbin or shippable metier cheese package, ready for use without further chemical processing. in the manufacture of staple fiber, the filaments from numerous spinnerets are combined into tow form, crimped, cut to the required length, and packaged in bales.
