Suppressing of Nonlinear Phase Noise in Dispersion Managed Quasi-Linear Transmission Systems

Abstract:

Dispersion and nonlinear effect of fiber is the main factor limiting the performance of the long-haul and high speed optical transmission system. This paper focuses on the analysis and modeling of nonlinear phase noise in quasi-linear optical transmission system. The analytical expression for the nonlinear phase noise is obtained basing on the first order perturbation theory. And the numerical calculation of the nonlinear phase noise is deduced. The calculation results show that when the noise source and the end point of the system is equidistant from the optical phase conjugation (OPC), the nonlinear phase noise added by the optical amplifiers can be compensated by the OPC located after the optical amplifiers.
