Abstract

Third order nonlinear effects and their interplay with chromatic dispersion are recognized as the main source of impairment of high bit rate systems. Recently a new approach [1], called mid-nonlinearity temporal inversion (MNTI) and based on the analysis of the temporal evolution of pulses, has arose great interest as it allows obtaining a significant reduction of nonlinear impairments without requiring a link re-design. So far attention has generally been paid to high bit-rate single channel transmission, where the effect of the dispersion slope can be assumed as negligible provided that the channel frequency is close to the central frequency of the optical-phase-conjugator (OPC).
