Abstract
An optical transmission system according to the present disclosure is a mode multiplexed optical transmission system using a multi-mode optical fiber in which a plurality of propagation modes propagate as a transmission line, the optical transmission system including an optical fiber transmission line () that includes an optical fiber with two or more propagation modes; and a plurality of mode converters () that are configured to generate mode coupling between at least one pair of the propagation modes, in which a variation in an installation interval of the plurality of mode converters () is equal to or less than a threshold value determined by the transmission line length (Lt) of the optical fiber transmission line ().
