HIGH BANDWIDTH MULTIMODE OPTICAL FIBER OPTIMIZED FOR MULTIMODE AND SINGLE-MODE TRANSMISSIONS |
摘要 |
It is proposed an optical fiber including an optical core and an optical cladding surrounding the optical core. The optical core has a refractive graded-index profile with a minimal refractive index n1 and a maximal refractive index n0. The optical fiber 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=√{square root over (n02−n12)}=n0·√{square root over (2&Dgr;)} with &Dgr; = n 0 2 - n 1 2 2 n 0 2 , &Dgr; is the normalized refractive index difference. The minimal and maximal refractive indexes n1, n0 and the optical core radius a are chosen such that NA>0.20, a>10 μm and |C|<0.20. |
