Multimode Dispersion
Multimode dispersion is defined as the delay-time dispersion resulting from the differences in group velocity among various modes in a multimode fiber. It arises due to the varying inclinations of
Digital communications: 2.4.1 Multimode distortion
Spreading due to multimode distortion limits the usable bandwidth of a fibre. Since the amount of spreading is proportional to distance, the bandwidth is inversely
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
