Abstract
A method of suppressing noise and improving the optical transmission characteristic of a wavelength division multiplexing transmission system provides lights for suppressing noise from the light sources (NS1 and NS2) which are multiplexed on the wavelength division multiplexed signal. Consequently, the S/N ratio of each channel of a wavelength division multiplexed signal which propagates through the optical path can be improved.
