Original Abstract Submitted

an object of the present invention is to provide an optical transmission system capable of reducing system costs and reducing waste of output power of a light source. the optical transmission system according to the present invention includes an ultraviolet light source part having a light emitting diode (led) that outputs ultraviolet light, an optical transmission line that propagates the ultraviolet light through a plurality of cores of a multi-core optical fiber or a plurality of cores of a bundle optical fiber obtained by bundling a plurality of single-core optical fibers, and an optical system that narrows down a spot shape of the ultraviolet light output from the led to a size including all of the plurality of cores in an optical axis direction, and causes the ultraviolet light to enter the plurality of cores.
