What is the broadening of a pulse due to the different path lengths taken through the fiber by different modes called?
A)Chromatic dispersion
B)Polarization mode dispersion
C)Diffusion
D)Modal dispersion

Question

Quizplus · Accepted Answer

Modal dispersion occurs in fiber optics when different modes (or paths) of light travel at different speeds through the fiber, causing the light pulse to spread out or broaden. This effect is significant in multimode fibers where multiple paths of light can travel.
