| In telecommunication, a graded-index fiber is an
optical fiber with a core having a
refractive index that decreases with increasing radial distance
from the fiber axis.
Note: The most common refractive index profile for a graded-index fiber is very nearly parabolic. The parabolic profile results in
continual refocusing of the rays in the core, and compensates for multimode distortion.
