Abstract
The present invention relates to a multimode optical fiber having a stably manufacturable structure as a transmission medium suitable for wide-band multimode transmission. In the multimode optical fiber, a core has a refractive-index profile a shape of which is defined by the exponent α which varies along a radial direction from a center of the core and an average of radial variation of which is positive in a predetermined range in the radial direction.
