Nonlinear and noise limitations in dispersion-managed soliton wavelength-division multiplexing transmissions with distributed Raman amplification
01 June 2001
We the study limitations to error-free transmission distance as set by noise accumulation and nonlinear pulse interactions in dispersion-managed N x 40-Gbit/s transmission systems with either distributed backward Raman amplification or lumped erbium-doped fiber amplifiers. Significant performance improvement is achievable with Raman amplification. (C) 2001 Optical Society of America.
