- 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

- 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).

- 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.)

- The transport of high voltage electricity. this is achieved with a transmission network (or grid). generally the network will connect large generators to lower voltage distribution networks where it will be transported to the majority of electricity consumers. alternatively, large scale electricity users may connect directly to the transmission network. management of transmission is a natural monopoly due to the economies of scale inherent to it. transmission system operator (tso) (also transmission network operator-
- The sending of information over a communications line or a circuit.
- The transportation of electric energy in bulk from a source or sources of supply to other systems or parts of a single system.

- (кан.) решение экспертизы
- N коммуни- кация; процесс передачи информации; mis~ недопонимание, непонимание | attr. комму- никативный disorder, impairment, strategy cross-cultural (intercultural) ~ межкультурная коммуникация non-verbal ~ невербальная, неречевая комму- никация verbal ~ вербальная, речевая коммуникация
- 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
Attenuation, английский

- Зависимость снижения мощности сигнала от расстояния. для оптоволоконных кабелей обычно выражается в дб/км
