Effect of group-delay ripples on dispersion-managed soliton communication systems with chirped fiber gratings

摘要

The effect of group-delay ripples in dispersion-managed soliton communication systems that use chirped fiber gratings for dispersion compensation is studied. Using both a reduced model and direct numerical simulation, we find that dispersion-managed solitons exist even in the presence of large dispersion variation caused by group-delay ripples. The dispersion-managed solitons suppress the growth of intersymbol interference induced by the group-delay ripples. (C) 2001 Optical Society of America. [References: 7]
