Abstract

The optimization of the performance of installed standard-monomode fibers based optical transmission systems with in-line semiconductor optical amplifiers (SOA's) is reported in this paper. Both solitons and nonreturn-to-zero (NRZ) signals are studied and their capacities are compared. This investigation is based on numerical simulations by solving the nonlinear Schrödinger equations with the split-step method while the SOA is simulated with two different models that we show to be in a good agreement. Transmissions over distances of the order of several hundreds of kilometers are shown to be possible, and very long distances can be reached expecially if in-line sliding filters are used.
