Abstract :
We report penalty-free 10 Gb/s single-channel transmission with co-pumped distributed Raman amplification using a novel high power, low RIN (relative intensity noise) multimode 14xx DFB pump. No penalty from pump to signal RIN transfer was observed up to 5 dB of co-pumped Raman gain. More than 200 mW from a single DFB pump was launched into the fiber without any SBS (stimulated Brillouin scattering).
