Abstract :
It is shown that the linear-wave growth in bandwidth-limited-amplified soliton transmission can be suppressed by a selective amplification of solitons by means of nonlinear gain that can be realized by using fast saturable absorbers. Numerical simulations assuming the use of nonlinear amplifying loop mirrors (NALM´s) as the nonlinear-gain element show that 20 Gb/s soliton trains can be transmitted over transoceanic distances, Wavelength-division multiplexing is also feasible if demulti/multiplexers are used just before and after the NALM
