T. Yu et al., Energy enhancement of dispersion-managed solitons in optical fiber transmission systems with lumped amplifiers, IEEE PHOTON, 11(1), 1999, pp. 75-77
We simulated dispersion-managed soliton propagation in optical fiber transm
ission systems with lumped amplifiers and loss. The energy enhancement of d
ispersion-managed solitons can be more or less than in the lossless case, d
epending delicately on the amplifiers arrangement. In all cases, there is a
maximum enhancement factor beyond which the dispersion-managed soliton no
longer exists and which also depends delicately on the arrangement.
