ABSTRACT:
A multimode optical fiber includes an inner core and an outer core on the inner core having different refractive index profiles. The refractive index profile of the outer core is graded, while the refractive index profile of the inner core may be graded. The refractive index profiles have the same value at the inner core--outer core boundary.
