SNR-Improvement of Four-Wave-Mixing Wavelength Converters using Raman Amplification

Based on a detailed experimental data-quality analysis of a FWM wavelength converter based on highly nonlinear fibres, we find significant improvement potentials, and demonstrate >1-dB SNR improvement of a converted 16-QAM, 32-Gbaud data signal by adding Raman amplification to the FWM process.
