Multimode Dispersion
Multimode dispersion cannot exist in a single-mode fiber, but two other mechanisms, material dispersion and waveguide dispersion, now come into play in limiting the bandwidth.
Modal dispersion
Modal dispersion is a distortion mechanism occurring in multimode fibers and other waveguides, in which the signal is spread in time because the propagation velocity of the optical signal is not the same for all modes. Other names for this phenomenon include multimode distortion, multimode dispersion, modal distortion, intermodal distortion, intermodal dispersion, and intermodal delay distortion. In the ray optics analogy, modal dispersion in a step-index optical fiber may be compared to multipath propagation
