%T Stimulated Raman scattering effect in the Silica-alumina fibers
%X We present experimental results of stimulated Raman scattering in silica-alumina fiber using the optical pump power combination scheme of middle-power laser diodes at wavelength of 1470-1471 nm. The optical single-pass gain of Raman fiber amplifier achieved up to 11 dB in the CW and 2.5 GHz modulated signal regimes at wavelength range of 1550 nm when the pumped power is of 29.54 dBm (900 mW) in silica-alumina optical fiber with the fiber length of 65-85 Km. This distributed-pump Raman fiber amplifier can be used in high-speed long-haul DWDM fiber optic communication networks.
