摘要：The invention relates to an optical link comprising N optical fibers, with N≧2.Each optical fiber comprises an optical core and an optical cladding surrounding theoptical core, the optical core having a single αi graded-index profile with αi≧1, and theoptical core having a radius R1i, where i E [1; N] is an index designating said optical fiber.Said optical cladding comprises a region of depressed refractive index ntrenchi, called atrench, surrounding the optical core. According to embodiments of the invention, for alloptical fibers in said link, said optical core radius R1i and said length Li are chosen suchthat R1i≧13.5 μm and so as to satisfy a criterion C of quality. Thus, the invention provides afew-mode optical fiber link, which allow guiding an increased number of LP modes ascompared to prior art FMF links, while reaching low Differential Mode Group Delay.
