Abstract
The present invention relates to a multimode optical fiber provided with a region where a refractive index in a peripheral region of a core has deviation from an ideal shape of an α-power refractive-index profile and where an absolute value of an amount of the deviation is not less than 0.005%, so as to generate radiation modes, and a refractive index of a cladding is higher than that of the deviation region.
