摘要： PROBLEM TO BE SOLVED: To provide an optical transmission system etc., having excellent noise characteristics. SOLUTION: The optical transmission system is provided with an optical fiber transmission line (20) in which signal light propagates, an optical device (30), and a Raman amplifier which is arranged upstream of the optical device (30). The optical device functions as an element to deteriorate the noise characteristics in a signal wavelength band from a long wavelength side to a short wavelength side when a desired gain is imparted to the signal light. On the other hand, the Raman amplifier performs Raman amplification of the signal light by adjusting the light power of the respective excitation channels included in excitation light in such a manner that the light power of the signal channels increases from the long wavelength side toward the short wavelength side of the signal wavelength band width in order to improve the noise characteristics over the entire part of the line (20). Since the Raman amplifier previously performs the Raman amplification of the signal light before the incidence thereof on the optical device (30), the influence of the optical device on the noise characteristics is relieved and the variations in the noise index over the entire part of the system are decreased.
