Effects of initial overlap in a wavelength-division-multiplexed soliton transmission system

Abstract

Initial overlap between solitons propagating at different carrier frequencies gives rise to a change in the frequencies of the solitons. The frequency change can have a severe effect on the transmission system because it will result in a time displacement of the solitons that is due to the fiber dispersion. The frequency change caused by initial overlap between two solitons at different carrier frequencies is calculated for a transmission system with periodic gain and loss.
