Abstract
Provided is a multimode optical transmission system capable of reducing an influence of multimode dispersion occurring when an optical signal is transmitted in multimode. Light sources (to) respectively convert inputted electrical signals into a plurality of optical signals respectively having different wavelengths, and respectively output the plurality of optical signals. A wavelength multiplexing section () performs wavelength multiplexing of the plurality of optical signals outputted from the light sources (to), and outputs a resultant signal as a wavelength multiplexed signal. A multimode optical transmission path () optically transmits the wavelength multiplexed signal in multimode. A mode processing section () extracts, from the wavelength multiplexed signal transmitted through the multimode optical transmission path (), a plurality of optical signals each being in a mode having a particular wavelength and a particular propagation constant. Optical receiving sections (to) receive the plurality of optical signals having been extracted, and convert the received optical signals into electrical signals.
