摘要： PROBLEM TO BE SOLVED: To provide an optical transmission system equipped with a structure for realizing signal transmission while maintaining excellent transmission characteristics over a broader wavelength band. SOLUTION: Signal light outputted from a signal light source (10) includes a positive chirp, is propagated through a transmission line fiber (30) and arrives at an optical receiver (40) after Raman-amplified by a lumped constant type Raman amplifier (20). The lumped constant type Raman amplifier (20) includes, as a Raman amplification fiber (130), a high nonlinear fiber that has a negative wavelength variance in a signal light wavelength and intentionally generates auto-phase modulation for the signal light. The positive chirp that the signal light propagated through the high nonlinear fiber has, is effectively compensated by the negative chromatic dispersion and the auto-phase modulation that occur within the high nonlinear fiber.
