Abstract:
1. A method for nonlinearity compensation for an optical transmission link comprising the steps of: determining a dispersion effect of a transmission link; applying a phase conjugation to the transmission link, said phase conjugation responsive to an input wave over said transmission link and providing a conjugated version of said input wave; and configuring an optimum equivalent link responsive to said phase conjugation after said transmission link to compensate for a non-linear dispersion effect from said transmission link; wherein said equivalent link comprises a configuration responsive to where Γ denotes an equivalence factor, L d(1) denotes a dispersion length of said transmission link, L d(2) denotes a dispersion length of said equivalent link, γ 1 denotes a nonlinear parameter of said transmission link; γ 2 denotes a nonlinear parameter of said equivalent link, P 1 (z) denotes a power evolution of said transmission link, and P 2 (z) denotes a power evolution of said equivalent link.
