Validation of Small-Signal Analysis for Nonlinear Dispersive Fiber Systems Using Numerical Simulation
The use of erbium-doped fiber amplifiers in optical communication systems operating at wavelengths near 1550 nm has increased the optical power in fiber links. This increase is limited by the presence of nonlinear effects. Among the nonlinear phenomena the optical Kerr effect plays a major role. This effect, per se or interacting with fiber dispersion, may impose severe system limitations with respect to the transmission bandwidth1,2.
