Abstract
Configurations of a Raman amplifier suitable for a 1.3-μm wavelength band are discussed and their properies are experimentally investigated. 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. Concerning the Raman laser, wavelength conversion from 1.06-μm to 1.23-μm is effectively achieved using a cavity configuration including fiber bragg gratings and a dispersion shifted fiber. On the other hand, a conventional dispersion compensation fiber which has an essential property of high non-linearity is applied in order to obtain large gain at 1.3-μm Net gain of 35 dB and ouput power of 15 dBm are achieved. To confirm the applicability of the Raman amplifiers to high-speed optical transmissions, 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 is obtained at both wavelengths, which is enough performance for a practical use.
