    摘要: The present document relates to an optical transmission system using multimode fibers. In particular, the present document relates to a method and system for coupling light into and out from multimode fibers. An optical coupling device (302, 304) configured to couple light between an array of light sources (211) or drains (221) and a multi-mode fiber (130) is described. The device comprises an array of first interfaces adapted to connect with the array of light sources (211) or drains (221), respectively; a second interface adapted to connect with the multi-mode fiber (130); an array of first lenses (401, 412), wherein a front side of each lens of the array of first lenses (401, 412) faces a corresponding first interface of the array of first interfaces; and a second lens (402, 412) at a backside of the array of first lenses (401,412) facing the second interface.
