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.

Mode Coupling Effects in Multi-Mode Fibers
In multi-mode fiber (MMF), a plurality of modes typically leads to modal dispersion, limiting the bit rate × distance product of direct-detection systems, so it was long viewed as a strictly negative effect.

Fiber dispersion measurements
For instance, in multimode fibers (especially step index), intermodal dispersion tends to be the dominant mechanism, whereas in single-mode fibers intermodal dispersion is nonexistent as only a single

Modal Dispersion
In multimode fibers, there are two dominant kinds of dispersion, modal and chromatic. Modal dispersion refers to the fact that different modes will travel at different velocities and cause pulse broadening.

Dispersion Analysis in Single Mode and Multimode Fiber
In multimode fibres and other waveguides, a distortion mechanism known as modal dispersion causes the signal to be spread out in time as a result of the various modes'' varying rates of propagation.
