Abstract:
A multi-wavelength light transmission system in which an optical amplification medium is installed on the transmission path through which multi-wavelength light is transmitted between a sending station and a receiving station, comprising:a light source installed within the sending station or near the sending station; a detector, installed within the sending station or near the sending station, detecting a number of multiplexed wavelengths in the multi-wavelength light; and a control circuit adjusting the power of the light emitted by said light source corresponding to the number of multiplexed wavelengths detected by said detector, wherein said sending station comprises: a plurality of transmitters outputting a plurality of optical signals to form the multi-wavelength light, respectively, having corresponding, mutually different wavelengths, and a splitting device splitting the plurality of optical signals and guiding the split optical signals to said detector, said detector detecting the number of multiplexed wavelengths based on the optical signals from said splitting device.
