Brillouin scattering in Raman-pumped fibers: An experimental investigation

In this paper, we present a report about the impact of the distributed second order Raman amplification on Brillouin Scattering in a long haul 100km fiber system experimentally. The second order lasers at 1486nm created by the primary pump at 1395nm amplify the signal centered at 1550nm and extend the Brillouin scattering distance. Experimental results show that, both the Brillouin scattering efficiency at high powers and the Brillouin threshold are reduced
