An optical transmission system is provided with a broadband optical transmitter including a broadband light source and a broadband optical modulator, an optical filter, an optical modulator, a transmission path, a wavelength router, and an optical receiver. The broadband optical transmitter outputs a broadband optical signal to the optical filter. The optical filter uses a branch wavelength bandwidth of the wavelength router as a basis for transmittance therethrough, and outputs only an applicable optical signal to the optical amplifier. The wavelength router simultaneously distributes the optical signal coming via the transmission path to each corresponding output port. In optical receivers, the optical signals penetrated through the wavelength router are converted into electrical signals.
