Loss windows
| Fiber Optic Glossary |
Fiber optic transmission typically occurs at 850, 1300/1310, 1550, and/or 1625 nm. these “windows” were selected because absorption and scattering losses were lower within them. these wavelengths require light sources and photodetectors that operate efficiently over multimode and single-mode fibers. the newer term “bands” is used to define optical windows that match up with optical amplifiers and their optimum transmission wavelengths

- 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-

Scattering, английский
- Утруска
- Intrinsic fiber losses caused by undissolved particles, boundary roughness, and intrinsic material losses
- Loss of light that is scattered off atoms in different directions, so it escapes from the fiber core. a major component of fiber attenuation.
- Рассеяние. процесс, в ходе которого происходит изменение направления или энергии падающей частицы или радиации, вызываемое столкновением с другой частицей или системой частиц (мос, 5). рассеяние ми — рассеяние электромагнитного излучения сферическими частицами при отсутствии четкой зависимости между размером частиц и длиной волны излучения. оно имеет большое значение для исследований по загрязнению атмосферного воздуха. свет интенсивно рассеивается частицами диаметром около 0,1—1 мкм; происходящее при этом снижение видимости является функцией квадрата радиуса частиц. рассеяние рэлея — рассеяние частицами, радиус которых меньше ую длины волны излучения (например, рассеяние света молекулами кислорода и азота в воздухе).

- The length of the light wave, usually measured from crest to crest, which determines its color. common units of measurement are the micrometer (micron), the nanometer, and the angstrom unit.
- The spatial period of a plane wave
- The distance between "waves" in the electromagnetic field, specified as angstroms or nanometers.
- The distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6m).
- The linear distance occupied by one complete cycle of vibration of an energy form from any given point to the next point characterized by the same phase.
- For light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. for light waves three common units of wavelength are: micrometer, nanometer, and angstrom. wave molding, oundy molding, swelled chamfer, undulating molding, undy
