Abstract
A bend-insensitive multimode optical fiber includes a core layer, and cladding layers surrounding the core layer. The core layer has a parabolic refractive index profile with α being 1.9-2.2, a radius being 23-27 μm, and a maximum relative refractive index difference being between 0.9-1.2%. The inner cladding layer has a width being 1-3 μm and a relative refractive index difference being between −0.05% and 0.1%. The trench cladding layer has a width being 2-5 μm and a relative refractive index difference being between −1% and −0.3%. The core layer is a Ge/F co-doped silica glass layer, where an F doping contribution at a central position of the core layer is less than or equal to 0%, an F doping contribution at an edge portion of the core layer is greater than or equal to −0.45%. The outer cladding layer is a pure silica glass layer.
