Encircled flux (ef)
| Fiber Optic Glossary |
Defined by iec 14763, tia 455-203, and ieee 802.3ae, ef is the most accurate test for determining optical attenuation for multimode fibers. most often used in factory environments due to its complexity and equipment costs

Определение о ~ reactions
Attenuation, английский
- The decrease in magnitude of a signal, as it travels through a medium. used to describe signal loss in a transmission system. measured in decibels (db).
- Поглощение
- Зависимость снижения мощности сигнала от расстояния. для оптоволоконных кабелей обычно выражается в дб/км
- In general terms, a reduction in signal strength.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or
- The difference between transmitted and received power due to loss through equipment, lines, or other transmission devices; usually expressed in decibels. the loss in power of electromagnetic signals between transmission and reception points.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or an electric system. it is measured in decibels (db).
- The loss of optical power, whether caused intrinsically (absorption, scattering, microbends, etc.), or extrinsically by components (connectors, splices, splitters, etc)
- The decrease in radiation energy (power) as a beam passes through an absorbing or scattering medium.
- Reduction of signal magnitude, or loss, normally measured in decibels. fiber attenuation is normally measured per unit length in decibels per kilometer. the decrease in signal strength along a fiber optic waveguide caused by absorption and scattering. attenuation is usually expressed in db/km.
- A reduction in the effect or strength of something such as a virus, either because of environmental conditions or as a result of a laboratory procedure
- Ослабление
- Ослабление (затухание). уменьшение количества радиации при ее прохождении через вещество в результате всех видов взаимодействия с этим веществом. ослабление обычно не связано с уменьшением геометрических размеров (мос, 5). ослабление солнечной радиации — потеря энергии световым лучом при его прохождении через атмосферу земли. потеря энергии обусловлена рассеянием света молекулами воздуха, селективной абсорбцией молекулами определенных веществ и рассеянием света аэрозолями (вмо).
- The weakening of a transmitted signal, such as the distortion of a digital signal or the reduction in amplitude of an electrical signal. attenuation is usually measured in decibels and is sometimes desirable, as when signal strength is reduced electronically, for example, by a radio volume control, to prevent overloading.
- The weakening of a transmitted signal, such as the reduction in the brightness of light, as it travels farther from its source.
- Regulatory system of prokaryotes whereby secondary stem-loop structures formed within the 5’ end of an mrna being transcribed determine both if transcription to complete the synthesis of this mrna will occur and if this mrna will be used for translation
- Decrease in transmitted energy intensity over distance. the loss may be due to absorption, scattering, reflection, leakage, beam divergence, or other material effects.
- Снижение интенсивности передаваемой энергии на расстоянии. потери могут быть вызваны поглощением, рассеянием, отражением, утечкой, расходимостью луча или другими материальными эффектами.
- Decrease in signal magnitude during energy transmission from one point to another. this loss may be caused by absorption, reflection, scattering of energy or other material characteristics or may be caused by an electronic or optical device such as an attenuator.1
- (1) decrease in energy or signal magnitude in transmission from one point to another. can be expressed in decibels or as a scalar ratio of the input magnitude to the output magnitude.16 (2) change in signal strength caused by an electronic device such as an attenuator. (3) decrease in intensity caused by absorption, leakage, reflection, scattering or other material characteristics. see also neper.
- (1) decrease in acoustic energy over distance. this loss may be caused by absorption, leakage, reflection, scattering or other material characteristics. (2) decrease in signal amplitude caused by acoustic energy loss or by an electronic device such as an attenuator.10,16,21

- Окружающая среда
- Окружающая среда; при- родно-ландшафтная среда
- The place in which an organism lives, and the circumstances under which it lives. environment includes measures like moisture and temperature, as much as it refers to the actual physical place where an organism is found.
- The combination of all the external conditions and the potential effect of the inner environment (heteromosaic of abiotic conditions). e. change: survival depends on the life span of the organisms involved, and has to adapt to a new situation via genetic change, evolution, etc. • cyclic change: rhythmically repetitive, like cycles of a season, day / night, movement of tides etc. • directional change: change is maintained over a long period in relation to the life span of organisms - erosion, siltation, cycles of glaciation, etc. • erratic change: these have no rhythm and no consistent direction e.g., hurricanes, cyclones, flash storms, fires, vulcanos, earthquake, etc.
- Окружающая среда. существующая в данный момент совокупность всех внешних условий и воздействий, которым подвержена данная система (или организм) (мос, 14). `36
- (1) the system of surrounding things, conditions or influences, especially affecting the existence or development of someone, something or another system (->habitat), (2) the art of environing, (3) the state of being environed.
- A global context in which to access data.
- A set of roles that are required to run a specific application and the machines to be used for each role.
- One of two deployment destinations within a microsoft azure cloud service: staging or production.
- The totality of surrounding conditions and circumstances affecting growth or development. often the term is applied to the natural features of a geographic area: water, air, and land — including ecological relationships.
- The sum of the physical, chemical, and biological factors that surround an organism.

E-band, английский
Defined by itu-t g.692 as “extended” for wavelengths between 1360 and 1460 nm. this band includes the high oh peak in single-mode fibers. g.652d fiber is designed for transmission within the extended band. in fttx systems, the term can be confused with the enhancement band, which the itu-t g.983 and g.984 pon fttx standards define as the wavelengths between 1550 and 1560 nm for rf overlay transmission of video signals
Premises, английский
- Defined as the subscriber’s home or place of business. in a multiple dwelling unit, each apartment is counted as one
- Land and/or its appurtenances.
- `premises` means buildings and land that goes with them (property), in which people live.
