Parmi les types de fibres actuellement disponibles, on distingue les fibres optiques «à saut d'indice» (ou à échelon d'indice) et les fibres «à gradient d'indice». Dans le premier cas, la variation radiale d'indice est brutale, à l'interface cœur-gaine, et la fibre est généralement constituée d'un cœur en silice dopée à l'oxyde de germanium, de phosphore, et d'une gaine en silice éventuellement dopée [...] à l'oxyde de bore. Ce sont ces oxydes dopants qui opèrent la différenciation des indices. Dans le second cas, la modification de l'indice de réfraction suit une loi parabolique : le rayon incliné s'éloignant de l'axe rencontre un milieu d'indice décroissant progressivement, ce qui a pour effet de le courber pour le ramener vers l'axe. 2, record 4, French, - %C3%A0%20gradient%20d%27indice

Graded-index multimode fiber contains a core in which the refractive index diminishes gradually from the center axis out toward the cladding. The higher refractive index at the center makes the light rays moving down the axis advance more slowly than those near the cladding. Also, rather than zig-zagging off the cladding, light in the core curves helically because of the graded index, reducing its travel distance. The shortened path and the higher speed allow light at the periphery to arrive at a receiver at about the same time as the slow but straight rays in the core axis. The result : a digital pulse suffers less dispersion. These fibers often become the physical medium for local-area networks. 2, record 10, English, - graded%2Dindex%20multimode%20fiber

pour comprendre la troisième famille, les fibres multimodes à gradient d'indice, on suppose qu'on sait réaliser deux lentilles, l'une classique, plan convexe, où le trajet optique à l'intérieur est de la forme ne(r), n étant l'indice et e l'épaisseur variable en fonction de la distance à l'axe r, et l'autre, plate, d'épaisseur e mais où l'indice, n varie en fonction de r de telle manière que n(r)e = ne(r). On en déduit aisément que ces deux lentilles focaliseront la lumière dans les mêmes conditions. La seconde, étant plate, peut être empilée avec des lentilles semblables qui réaliseront une convergence permanente des rayons. Si la loi d'indice est quasiment parabolique, des rayons issus d'un même point reconvergeront périodiquement aux mêmes endroits, réalisant un guidage parfait. De telles fibres présentent aujourd'hui des bandes passantes supérieures à 1 gigahertz. 2, record 10, French, - fibre%20multimode%20%C3%A0%20gradient%20d%27indice
