High bandwidth multimode optical fiber optimized for multimode and single-mode transmissions

Abstract

It is proposed a home optical data network formed of an optical fiber comprising an optical core and an optical cladding surrounding the optical core, the optical core having a refractive graded-index profile with a minimal refractive index n1 and a maximal refractive index n0, said optical fiber being such that it has a numerical aperture NA and an optical core radius a satisfying a criterion C of quality of optical communications defined by the following equation: C = NA - 0.02 × a where ⁢ : NA = n 0 2 - n 1 2 = n 0 · 2 ⁢ Δ ⁢ ⁢ with ⁢ ⁢ Δ = n 0 2 - n 1 2 2 ⁢ n 0 2 , Δ is the normalized refractive index difference, and in that said minimal and maximal refractive indexes n1, n0 and said optical core radius a are chosen such that NA>0.20, a>10 μm and |C|<0.20.
