Optical fiber transmission systems using stimulated Raman scattering: Theory

Forward and backward stimulated Raman scattering is theoretically discussed. For forward stimulated Raman scattering, the discussion is made taking account of the pump depletion due to the stimulated Raman scattering process. On the basis of the results, the optical transmission systems using stimulated Raman scattering are discussed and the possibility of repeater spacing more than 400 km is presented.
