Abstract
A multimode optical fiber () comprises an a-profile graded index core, a trench () surrounding the core () and an intermediate cladding () between the core and the trench. Such a multimode optical fiber () has: —A mode carrying capacity between 54 and 68 LP modes at 1060 nm, defined by a specific relationship between the numerical aperture of the core and the core radius, —A defined relationship between trench, core and intermediate cladding parameters to achieve a high bandwidth and low bend-loss at 1060 nm, and—A core radius between 24 and 26 μm, a numerical aperture between 0.190 and 0.225 and a value of a between 2.01 and 2.05 to retain compatibility with legacy fibers.
