The optical transmission system of the present invention includes a multi-core transmission path which includes a plurality of cores, and in which optical signals propagate through the plurality of cores, a first optical repeating means for amplifying the optical signals by individually exciting first multi-core optical amplification mediums, and a second optical repeating means for amplifying the optical signals by collectively exciting second multi-core optical amplification mediums, wherein the first optical repeating means is positioned spaced apart from the second optical repeating means by a distance determined on the basis of either a first transmissible distance due to the first optical repeating means and a second transmissible distance due to the second optical repeating means.
