Abstract

In the context of single-channel quadrature phase-shift keying dispersion-managed transmission systems, we numerically investigate the signal impairments due to the deterministic interaction between chromatic dispersion and nonlinearities. We first observe that received signal constellations exhibit an average optical phase shift exceeding the nonlinear cumulative phase. We then show that this exceeding phase shift yields useful indications for the optimization of dispersion-managed system design.
