In____ multimode fiber-optic cable, signals all arrive at the same time and with less long-distance distortion than the other type of multimode fiber-optic cable.
A)step-index
B)even-index
C)graded-index
D)single-index

Question

Quizplus · Accepted Answer

Graded-index multimode fiber-optic cable has a core that gradually increases in refractive index toward the edges, which helps to limit the dispersion of signals and reduce distortion over long distances compared to step-index multimode fiber-optic cable. Even-index and single-index are not valid types of multimode fiber-optic cable.
