Abstract
Disclosed is a multimode optical fiber having a structure to reduce scattering loss which includes a core divided into a central region having the optimal refractive index according to an optimal core shape index minimizing the scattering loss of the multimode optical fiber, and a peripheral region having the refractive index lower than that of the central region; and a cladding enclosing the core and having the refractive index lower than the lowest refractive index of the core.
