Intermodal Dispersion

Explanation:

As multimode graded index fibers show substantial bandwidth improvement over multimode step index fibers. So, inter-modal dispersion in multimode fiber is minimized with the utilization of multimode graded index fibers.

One way to scale back modal dispersion is to use graded-index fiber. Unlike the 2 distinct materials during a step-index fiber, the graded-index fiber's cladding is doped in order that the index of refraction gradually decreases over many layers. The corresponding cross-sections of the fiber types are shown below.

In fiber-optic communication, an intramodal dispersion, may be a category of dispersion that happens within one mode glass fiber. This dispersion mechanism may be a results of material properties of glass fiber and applies to both single-mode and multi-mode fibers.
