Abstract

Optimum design of S-band negative dispersion DCF discrete fiber Raman amplifier has been researched by OPTIAMP DESIGN 3.3 SOFTWARE (made in Canada Optiwave Corporation). Simulated result is following: The optimum fiber is 6.4km. The small signal pump on/off gain spectrums have been got, During different back-direction pump power. The backscattering spectrum of optical fiber has been measured by use 1427nm Raman laser and Q8384 optical spectrum analyzer and Stokes and anti-Stokes ZX band backscattering spectrum has been first observed and discussed, zx band frequency shift is 1THz, band width 3THz(3dB).gain spectrum and gain vs. power of DCF discrete fiber Raman amplifier have been measured, practical including Stokes ZX band backscattering gain effect. Pump on/off small signal gain is 13dB (pump power 700mw; fiber 5. 1km) and gain band width is 88nm (1440nm-1528nm).
