Abstract

Hybrid FRA is consists of distributed FRA and discrete FRA. Optimum design of S-band hybrid dispersion compensation fiber Raman amplifier has been researched by OPTIAMP DESIGN 3.3 software (made in Canada Optiwave Corporation) and gain spectrum and gain vs. power of S-band hybrid dispersion compensation fiber Raman amplifier has been researched. 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). Pump on/off small signal gain is 23dB (pump power 700mw; G652 fiber 25.2km and DCF fiber 5.1km) and gain band width is 96nm (1440nm-1536nm). In the experiment, gain spectrum band width is wider than simulated results, practical including Stokes ZX band backscattering gain effect.
