[en] The present invention relates to a multimode optical fibre comprising from the centre to the periphery an optical core and a cladding having a refractive index defined by n cladding , wherein the core has a radius (r 1 ) and an +- refractive index profile with a graded index with respect to the cladding, the maximum refractive index of the core being n max and the minimum refractive index of the core being n min , in which n min - n cladding > 2x10 -3 , the fibre exhibiting a bending loss of less than 0.1 dB for two turns for a radius of curvature of 15 mm. The cladding is in direct contact with the core. The invention thus makes it possible to obtain a graded-index fibre having reduced bending losses with coupling losses to a standard graded-index fibre which are more limited than in the state of the art.
