Abstract
A general small-signal theory for nonlinear dispersive optical fiber systems with in-line amplification is investigated and validated through numerical simulation for different dispersion propagation regimes, optical powers, and number of fiber segments. This theory allows for any arbitrary phase and intensity modulation at the transmission system input from which phase and intensity at the transmission system output are derived. It is shown that in case of anomalous dispersion regime the conversion factors between power and phase can be remarkably enhanced and their dips move towards higher frequencies as the number of fiber sections increases, even for moderate powers. In case of normal dispersion regime, all conversion factors can be significantly reduced and their dips move towards lower frequencies as the number of fiber sections increases.
