A) multimode fiber
B) single-mode fiber
C) both A and B
D) neither A nor B

Question

Quizplus · Accepted Answer

Modal dispersion is a phenomenon that primarily affects multimode fiber, as it occurs due to the different paths (modes) that light can take through the fiber, leading to different arrival times at the receiver. Single-mode fiber, by design, supports only one path, virtually eliminating modal dispersion as a limiting factor.
