Intermodal dispersion in multimode fibers is minimized with the use of step-index fibers.

The correct answer is False.

Intermodal dispersion is a type of dispersion in optical fibers that occurs when light travels through multiple paths of different lengths within the fiber. This causes the light to arrive at the destination at different times, which can lead to signal distortion.

Step-index fibers have a sharp boundary between the core and cladding materials, which causes light to travel in multiple paths. This is in contrast to graded-index fibers, which have a gradual transition between the core and cladding materials, which causes light to travel in a single path.

As a result, intermodal dispersion is minimized in graded-index fibers, not step-index fibers.
