The invention provides a graded-refractive index multimode optical fiber presenting a refractive index profile given by the relationship where: n0 is a refractive index on an optical axis of the fiber; r is a distance from said optical axis; a is a radius of the core of said fiber; [Delta] is a non-dimensional parameter, indicative of an index difference between the core and a cladding of the fiber; and [alpha] is a non-dimensional parameter, indicative of a shape of an index profile and lying in the range 2.0 to 2.1; the optical fiber being characterized in that its -3 dB bandwidth as a function of radial offset from an axis of the fiber, as measured at a wavelength 850 nm, is greater than or equal to 6000 MHz.km for all radial offsets lying in a range 0 to R1, where R1 lies in a range 0.7 to 0.9 times the radius of the core of the fiber, preferably wherein R1=18 [micro]m and presenting the core having a diameter of 50 [micro]m.
