    Abstract: PURPOSE: To provide a lumped constant type Raman amplifier which is suppressed in the deterioration of the transmission quality of signal light due to nonlinear optical effect and an optical transmission system which uses it. CONSTITUTION: An optical transmission line in the Raman amplifier 1 which transmits the signal light inputted from an input terminal 1a and also processes the signal light by Raman amplification with the exciting light supplied from exciting light source units 21 and 22 is constituted by connecting two optical fibers 11 and 12 for Raman amplification in series, and they are set to mutually different wavelength dispersion values. This constitution makes it possible to control the wavelength dispersion in the amplifier 1 by using a combination of the wavelength dispersion values of the optical fibers 11 and 12 for Raman amplification, etc. Consequently, the deterioration in the transmission quality of the signal light due to nonlinear optical effect is suppressed by preventing dispersion from being accumulated in the signal light and the signal light from being transmitted nearby zero dispersion.
