Abstract
The present invention relates to a multimode optical fiber including a glass fiber, and a coating member provided on an outer periphery of the glass fiber. The glass fiber extends along a predetermined central axis, and includes at least a core region having a GI-type refractive index profile. The coating member has a refractive index that is higher than a minimum refractive index of the core region. According to this configuration, leakage of a higher-order mode with a large group delay difference to the coating member side is facilitated.
