Dispersion-shifted fiber — (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation. Dispersion Shifted Fiber is a type of single mode optical fiber with a core clad index profile tailored to shift the zero dispersion wavelength from the… … Wikipedia
Attenuation — Atténuation Diagramme d atténuation d un signal électromagnétique dans l atmosphère selon la fréquence L’attenuation est la réduction de l amplitude et de l énergie d un signal à travers le médium qu il traverse. Cette perte peut être… … Wikipédia en Français
Attenuation — This article is about attenuation in physics. For other uses, see Attenuation (disambiguation). In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance … Wikipedia
