1. intermodal dispersion in multimode fibre but intrmodal in single mode....

2.intermodal is also known as modal dispersion but intramodal is also known as material dispersion.

3.in intermadal more pulse broadning but in intramodal less pulse broadning.

In optical fibers, multi-path dispersion occurs in a wide core because light travelling along the axis of the core travels a shorter distance per metre of a fiber than light that repeatedly undergoes total internal reflection. A pulse of light sent along a wide core would become longer that it ought to be. If it was too long, it would merge with the next pulse.

the three types of dispersion are:

1. Intermodal Dispersion

2. Chromatic Dispersion

3. Waveguide Dispersion

The manner in which members of a population are arranged in a particular area is know as dispersion. There are three main kinds of dispersion, which are clumped dispersion, random dispersion, and uniform dispersion.
