Abstract :
We realized a discrete Raman repeater with the dispersion and dispersion slope compensation over seamless bandwidth of 100 nm by using DCF. The gain flatness after transmitting the transmission line was 2.3 dBp-p, and the OSNR was from 34.5 dB to 39.3 dB. We also estimated the improvement of gain flatness by using nine wavelengths of pumping lights, and we theoretically realized the 0.5 dB gain flatness Raman amplifier.
