TL;DR: Two synchronously self-pulsing GaAlAs lasers, emitting at slightly different wavelengths, are combined in a setup which evaluates mode and material dispersion in multimode fibers, and results show that material Dispersion may represent a serious limit to the bit rates achievable in a multimode fiber system using an LED source.
Abstract: Two synchronously self-pulsing GaAlAs lasers, emitting at slightly different wavelengths, are combined in a setup which evaluates mode and material dispersion in multimode fibers. The results show that material dispersion which causes a pulse broadening of 3.6 ns/km, which may represent a serious limit to the bit rates achievable in a multimode fiber system using an LED source.

TL;DR: In this paper, the effect of refractive index profiling in multimode fibres on modal time-delay differences and modal wavelength dispersion has been evaluated and shown that the delay can be made negligible compared with the modal dispersion, which is comparable in magnitude but opposite in sign, to glass dispersion.
Abstract: The effect of refractive-index profiling in multimode fibres on modal time-delay differences and on modal wavelength dispersion is evaluated. The delay can be made negligible compared with the modal dispersion. The latter is comparable in magnitude, but opposite in sign, to glass dispersion.
