“…The effect of the saturation of the optical amplifiers by the ASE noise is inhibited by the use of in-line optical filters with a bandwidth of 640 GHz. With a good approximation, assuming a constant GVD along the link, the bandwidth in which the nonlinear interaction between signal and ASE manifests is of the order of where is the GVD [9].…”

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.
