Optical Fibre optimized for the Reduction of Nonlinear effects

An optical fibre designed to simultaneously attenuate the effect of modulation instability and stimulated Raman scattering. A first solution proposes to use non-zero dispersion shifted fibres in the normal dispersion regime to reduce both influences at the same time. A further solution proposes to implement corresponding filter elements in the signal line. A still further solution proposes to additionally provide absorber elements for the Raman wavelengths or to design the core as a leaky one for these wavelengths.
