Input pulse optimization in wavelength-division-multiplexed soliton transmissions

Abstract Amplitudes of input pulses in different channels of wavelength-division-multiplexed soliton transmissions should be adjusted according to their wavelength shift. The optimal distribution of input amplitudes maintains the initial time width and minimizes the radiations. Numerical simulations indicate that using this simple method, WDM transmission capacities of 80 Gbit/s over transoceanic distances may be possible in dispersion-managed fiber links without introducing any in-line soliton controls.
