We simulated dispersion-managed soliton propagation and interaction in
optical fibers. The energy-enhancement factor, together with the time
-bandwidth product and the stretching factor, were calculated as a fun
ction of the difference in absolute values of accumulated dispersion i
n the fiber spans. The interaction strength of the dispersion-managed
solitons was found to depend on the stretching factor. When this facto
r is less than 1.5, the interaction is weaker than for ideal solitons.
When it is more than 1.5, there is a strong interaction between the p
ulses, which constrains the energy enhancement for practical applicati
ons. (C) 1997 Optical Society of America.
