1. An optical transmission system comprising:
N transmitters configured to convert N electrical signals indicating N data sequences different from one another into N optical signals, respectively, N being an integer of 1 or more;
a signal generator configured to convert the N optical signals into first M optical signals by splitting the N optical signals via N optical splitters, M being an integer of 2 or more, M being larger than N;
a multiplexer configured to convert the first M optical signals into one mode-multiplexed signal that is excitable in at least M modes;
a demultiplexer configured to receive the one mode-multiplexed signal via a mode-multiplexed fiber and convert the one mode-multiplexed signal into second M optical signals;
M receivers configured to convert the second M optical signals into M electrical signals, respectively; and
a signal detector configured to extract the N data sequences by performing signal separation on the M electrical signals.
