B)absorptive attenuation
C)both A and B about equally

Question

Quizplus · Accepted Answer

Multimode fiber distance is primarily limited by modal dispersion, which occurs when the different modes or paths of light inside the fiber arrive at the end at different times, causing the signal to spread and become distorted. Absorptive attenuation, which is the loss of signal strength due to absorption by the fiber, is also a factor in limiting distance, but it is not as significant as modal dispersion for multimode fiber.
