Optical path power penalty
| Fiber Optic Glossary |
The additional loss budget required to account for degradations due to reflections, and the combined effects of dispersion resulting from intersymbol interference, mode-partition noise, and laser chirp.

Additional, английский
- Дополнительный 33
- Дополнительный; добавочный
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.
Dispersion, английский
- Увеличение ширины импульса сигнала при его распространении по оптоволокну. основной фактор, ограничивающий полосу пропускания многомодового оптоволокна.
- Дисперсия.
- Эффект расширения световых импульсов во время их передачи по оптическому волокну. дисперсия пропорциональна длине кабеля (см. также хроматическая дисперсия).
- Refers to the spread of values observed for a variable. the standard deviation is a measure of dispersion, in contrast to the mean which is a measure of central tendency or location.
- The cause of bandwidth limitations in fiber. in multimode systems, modal dispersion is caused by differential optical path lengths known as differential path delay. for singlemode systems, chromatic dispersion is a combination of material dispersion (caused by the line width of the laser source) and waveguide dispersion (caused by the difference in the speed of light in the core and the cladding of the fiber). another type of dispersion is polarization mode dispersion (pmd), which is caused by random vibration, temperature variations, and bending of the fibers known as birefringence
- (1) the variation in the refractive index of a medium as a function of wavelength. (2) the property of an optical system which causes the separation of the monochromatic components of radiation.
- The dependence of the phase velocity in a medium on the optical frequency or the propagation mode
- The stretching of light pulses as they travel in an optical fiber, which increases their duration. the temporal spreading of a light signal in an optical waveguide caused by light signals traveling at different speeds through a fiber either due to modal or chromatic effects.
- This occurs when white light is split into separate wave lengths and component colors.
- Модовая дисперсия dispersion-compensating fiber волокно с компенсацией дисперсии
- Also known as "fire," dispersion refers to the separation of white light into different colors.
- Separation of white light into spectral colours, each of which vibrates at a different frequency. also called fire.
- Sometimes referred to as fire, dispersion is the break-up of white light into a spectrum of colors.
- 1. a system consisting of finely divided particles and the medium in which they are distributed. 2. separation of light into colors by diffraction or refraction. 3. a qualitative estimation of the separation and uniform distribution of fibers in the liquid during the production of a wet-formed nonwoven fabric.
- Losses`, pi потери воды при капельном орошении за счет фильтрации за пределы очага увлажнения
- The separation of light of different frequencies due to different degrees of refraction
- In acoustics, variation of wave phase with frequency.
- In acoustics, variation of wave phase with frequency.7
Interference, английский
- Effect caused by the introduction of unwanted electrical signals into an electrical circuit. in cctv this results in "noise" in the signal or picture, which disrupts the picture.
- Extraneous energy which tends to interfere with the reception of the desired signals.
- Disturbances of an electrical or electromagnetic nature that introduce undesirable
- “artifactual increase or decrease in apparent concentration or intensity of an analyte due to the presence of a substance that reacts nonspecifically with either the detecting reagent or the signal itself.” [clsi]
- Signal
- Столкновение прав (заявляемых или патентных); приоритетный спор
- A scrambling of the content of signals by the reception of desired signals.
- Disturbances of an electrical or electromagnetic nature that introduce undesirable responses in other electronic equipment.
- A range of phenomena associated with the superposition of waves
- For light, the way that waves add together, depending on their phase. constructive interference occurs when the waves are in phase and their amplitudes add. destructive interference occurs when the waves are 180 degree out of phase and their amplitudes cancel.
- N интерференция interfix n интерфикс
- The static and other noises sometimes heard over the phone line.
- Столкновение одновременно заявляемых прав на патент
- Distortion of a light wave due to interaction with another wave
- A proceeding, conducted before the patent trial and appeal board, to determine priority of invention between a pending application and one or more pending applications and/or one or more unexpired patents under pre-aia u.s. patent law.
- A proceeding conducted before the board of patent appeals and interferences to determine the priority of invention between a pending application and one or more pending applications and one or more unexpired patents.
- The negative effect of a learners first language(s) on the learning of a target language.
- Помехи, наводки

Channel spacing, английский
- The amount of bandwidth allocated per channel.
- Канальный интервал
Spectral width, full width, half maximum (fwhm), английский
The absolute difference between the wavelengths at which the spectral radiant intensity is 50 percent of the maximum power.
