Optical fiber
| Telecommunications Glossary |
- An extremely thin, flexible thread of pure glass able to carry one thousand times the information possible with traditional copper wire. see fiber optics.
- An optical waveguide comprised of a light-carrying core and cladding, which traps light in the core. fiber optic communication systems use either single-mode or multimode types
- A filament of quartz or other optical material, capable of transmitting light along its length by multiple internal reflections and emitting it at the end.
- 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.
- The thin, clear glass fiber used in phone networks to carry signals. see fiber optics.

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, шведский
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

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
Fiber channel arbitrated loop, английский
Information, английский
- Knowledge of a particular event or situation, or knowledge communicated or received concerning a particular fact.
- Информация
- Facts about something have you any information about the treatment of sunburn? the police won’t give us any information about how the accident happened. you haven’t given me enough information about when your symptoms started. that’s a very useful piece or bit of information. (note: no plural: some information; a piece of information.)
- N информация | attr. информационный flow, structure source of ~ источник информации 1 ранее использовался в более широком значении как ‘умозаключе- ние’. 2 получение выводных данных в процессе обработки информации и/или языка и само выводное знание, умозаключение; мыслительная операция, в ходе которой человек выходит за пределы данных в тек- сте сведений и получает новую информацию. 3 аффикс, вставляемый внутрь корня слова при словообразовании или словоизменении.
- In admiralty courts, implies a clause introduced into a citation, intimating that in the event of a party cited not appearing, the court will proceed in his absence.

- Передача (распространение) информации процесс информирования населения.
- Corresponding by letter, hail, or signal. (see line of communication and boyaux.)
- Loosely, the transmission of structure across systems differentiated in time and in space, the process by which one mind affects another, interaction mediated by signals, symbols or messages. more formally and in cybernetics, communication is that construct an observer requires when he cannot take a dynamic system apart without loss (->ana~ysis), yet wants to distinguish, understand and say something about that system`s parts, variables or members, or alternatively, when he wants to explain the behavior of anyone of its parts yet cannot accomplish this adequately without reference to other parts of the system. communication ~s what integrates and distinguishes the participation of individuals in such wholes as groups, communities, societies. a more detailed analysis of communication processes reveals that they involve patterns that convey information, are subjected to numerous constraints and are describable in terms of transformations, including encoding, decoding, (->coding), transmission, and distortions due to the characteristics of a channel. historically, communication. was thought of as a binary relation between a sender and a receiver. modern conceptions of communication include complex networks possibly with feedback loops having the effect of memory, coordination, and coorientation and exhibiting dynamic properties not manifest in, and explainable by, reference to the properties of the.communicators involved (->constructivism). communications (plural

Reflections, английский
Out-of-control reflections can hurt your image; controlled ones can enrich it. tips: keep the subject in full sun, the reflecting surface, such as water, in shade. reflections on water are most pronounced when the lens is at a low angle. most mirrors add a greenish cast to the image. normal mirrors add a "ghost reflection" to the main reflection; use a first surface mirror for critical images.

Orange book, английский
- Colloquial name of the standard that describes cd-recordable equipment, media and formats. an extension of the yellow book standard which includes specifications for incremental writes or multiple sessions. it specifies standards for cd-r and magneto-optical cartridge systems as well as kodak`s photo cd. most cd-rom drives today can only read single session discs or the first session of a multisession disc.
- "оранжевая книга"; "критерий оценки пригодности компьютерных систем (tcsec)"
- The format that enables cd-r drives to record discs that regular cd-rom players can read. orange book defines how cd-r devices can append index data to an existing disc’s directory if you add more data to the disc in multiple sessions. orange book ~
Optical character recognition - ocr, английский
