C)Both A and B about equally.

Question

Quizplus · Accepted Answer

Multimode fiber distance is primarily limited by modal dispersion, which occurs when light travels through multiple paths (modes) within the fiber, causing differences in arrival time and resulting in signal distortion. Absorptive attenuation may also impact the distance, but it is a secondary factor compared to modal dispersion.
