摘要：An object of the present invention is to realize almost the same transmissioncharacteristic in all wavelengths at a transmission rate of 10Gb/s or more. An opticaltransmitter 10 outputs WDM signal light multiplexed with signal light of a plurality ofwavelengths toward an optical transmission line 12. The optical transmission line 12comprises an optical transmission fiber 14, an optical repeating amplifier 16 and adispersion compensating fiber 18. The gain characteristic of the optical repeating
amplifier 16 is set so that the gain becomes the maximum at the effective zero dispersionwavelength of the optical transmission line 12 and that lowers inversely proportional to
the distance from the effective zero dispersion wavelength. The whole optical
transmission line 12 is set so that the peak power deviation between the effective zerodispersion wavelength λ0 and the wavelength λ1 or λn on both end becomesapproximately 4 dB.
