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 Schrodinger 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 especially if in-line sliding filters are used
