Abstract

Raman-only amplification (combined discrete and distributed or discrete only)1,2 and all distributed Raman amplification3 have recently demonstrated applications in WDM transmission systems. A lot of interest was raised, as to whether all-Raman amplification is better than the widely used counter-pumped Raman/EDFA hybrid amplification. A theoretical comparison with a 10 Gb/s-based standard SMF system at a span length of 100 km was recently reported.4 Double Rayleigh scattering (DRS)4,5 was suggested as the major limiting factor for all-Raman systems.
