Electrostriction-induced acoustic effect in ultralong-distance soliton transmission systems.

The electrostriction-induced acoustic effect introduces a time-dependent index evolution for the following optical pulses and results in an additional temporal shift of solitons. The acoustic effect is incorporated into the nonlinear Schrödinger equation as a perturbative term. We investigate the evolution of timing jitter, taking into account both the Gordon-Haus and the acoustic effect contributions for a 10-Gbit/s sliding-frequency in-line-filter soliton system.
