Abstract
AbstractIn this paper, the mutual interaction of adjacent pulses is studied as a cause for degradation of the transmission quality of a dispersion‐managed (DM) soliton. It is shown that the variation of the pulse spacing due to the mutual interaction between two DM solitons can be made extremely small by appropriately selecting the incident pulse spacing and the transmission line parameters. Next, the averaging method is applied to two DM solitons in the parameter region in which the effect of this mutual interaction becomes extremely small. It is shown that there exists a bi‐soliton as a steady solution with two main lobes. Its nature is discussed in detail. Further, a novel transmission line coding scheme using this bi‐soliton is worked out and a method to reduce the interpulse mutual interaction is proposed. © 2002 Wiley Periodicals, Inc.
