WebDec 22, 2024 · However, things are different if one uses a graded-index multimode fiber. Although the light rays travel in different modes as well, the modal dispersion will be greatly decreased because of the various light … WebA step-index profile is approached in the limit of large α. A parabolic-index fiber corresponds to α = 2. It is easy to understand qualitatively why intermodal or multi path dispersion is reduced for graded-index fibers. As shown in the above picture, three different rays take three different paths. The path is longer for more oblique rays ...
