WebThere are two main categories of optical fibers: single-mode and multimode.. “Mode” refers to a ray of light traveling down the fiber. Multimode (multiple rays of light) fiber is further classified as either graded-index or step-index. The index profile describes the way the multiple rays of light travel down the fiber.
