Abstract
The spectral distortion introduced by stimulated Raman scattering (SRS) in an optical fiber transmission system has been determined to always be linear on a dB/nm scale and depend solely on the total input power and not on the input power distribution. By maintaining the total input power to the fiber constant, the resulting Raman gain tilt may be compensated for or canceled by using an optical filter.
