Graded index fibers produced by liquid-phase melting technique are less dispersive than step-index fibers.

Question

Quizplus · Accepted Answer

Graded index fibers have a refractive index that gradually changes across the diameter of the fiber, which reduces modal dispersion compared to step-index fibers where the refractive index abruptly changes between the core and cladding. This makes graded index fibers less dispersive, allowing for more efficient signal transmission over longer distances.
