Abstract
The present invention embraces a multimode optical fiber that includes a glass-based central core having an alpha-index profile and a glass-based cladding immediately surrounding the optical fiber's central core. Typically, the refractive index difference between the central core's minimum refractive index and the cladding's maximum refractive index is greater than 2×10. The multimode optical fiber exhibits reduced bending losses and reduced coupling losses when connected to a standard graded-index fiber.
