Multimode Fiber

Fibers that carry more than one mode are called multimode fibers. There are two types of multimode fibers. One type is step-index multimode fiber and the other type is graded-index multimode fiber.

Step-index multimode fibers are mostly used for imaging and illumination. Graded-index multimode fibers are used for data communications and networks carrying signals moderate distances - typically no more than a couple of kilometers.
