Abstract(in English) A Raman amplifier suitable for a 1.3-μm wavelength band is experimentally studied and net gain of 35dB and output power of 15dBm are achieved. A pump light with a wavelength of 1.23-μm that is necessary for the Raman amplification in the 1.3-μm wavelength band is obtained using a 1.06-μm fiber laser and a Raman laser technique. A conventional dispersion compensation fiber which has an essential property of high non-linearity is applied in order to obtain large gain at 1.3μm. Experiments of 20 Gbit/s×2 WDM repeaterless transmission through a 80-km conventional single mode fiber is carried out. The 1.3-μm signal should be degraded due to the dispersion caused by the dispersion compensation fiber in the Raman amplifier. However, bit error rate of less than 10^<-12>which is enough performance for a practical use is obtained.
