Abstract

The Amplification Effect on SBS and Rayleigh Scattering in the backward pumped G652 Fibers Raman Amplifier have been researched, pumped by the tunable power 1427.2nm fiber Raman laser and signal source is a tunable narrow spectral bandwidth (<;10MHz) ECL. The Rayleigh scattering lines are amplified by fiber Raman amplifier, and Stokes stimulated Brillouin scattering lines are amplified by fiber Raman amplifier and fiber Brillouin amplifier. The SBS lines total gain G_A is production of the gain of Raman G_R and the gain of Brillouin amplifier G_B G_A = G_R · G_{B .} In experiment, the gain of SBS is about 42dB and the saturation gain of 25km G652 backward FRA is about 25dB, so the gain of fiber Brillouin amplifier is about 17dB.
