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. WebMulti-mode Optical Fibers. Multi-mode optical fiber has a core diameter that is much larger than the wavelength being carried. The large core allows for high numeric apertures for superior light gathering compared to single mode fibers. We offer graded index, step index, and power delivery multimode fibers to meet most bulk light transport ...
