Introduction of electrostriction-induced acoustic interaction in modeling of high-capacity long-haul transmission systems

We present a method to implement an electrostriction-induced acoustic effect in the nonlinear Schrodinger equation (NLSE) and to validate it from a system point of view, in particular, by comparison with experimental results. Special focus is devoted to acoustic cross effects between channels in wavelength-division multiplexing (WDM) transmission. The model is then applied to different realistic single-channel 40-Gb/s soliton systems in the presence of dispersion management or in-line optical regeneration to evaluate induced penalties.
