Quasi-stable soliton in periodic dispersion-managed fibre links with asymmetric dispersion maps

The authors show that pulse propagation in a periodic dispersion managed system with an asymmetric dispersion map is distinguished by transient fluctuations. For some dispersion allocations, the transient settles after one soliton period into a quasi-stable state provided that the soliton energy is optimised. The range of dispersion maps that satisfies different stability criteria, or that maximises some figure of merit, is identified
