Graded-index fiber is a type of optical fiber that is designed to reduce signal loss and distortion by varying the refractive index of the fiber's core in a specific gradient. This gradient, which typically decreases from the center of the core to its outer edge, helps to minimize modal dispersion—one of the main limitations in multimode fibers.
