We consider recent developmet in the theory and numerical
modelling of dispersion manged solitons in fiber optics.
Solitons have been considered as the 'natural bits' in
high-speed optical fibre communications for more than 25
years, due to their natural ability to balance the effects
of fibre dispersion and nonlinearity.
However the implementation of the conventional solitons in
homogeneous fibers had no significant advantages against
quasi-linear propagation regimes.
Only recently, during the last few years the break through happened in
utilizing the soliton-based transmission.
This rapid progress has been driven by the application
of dispersion management techniques to soliton transmission,
and the subsequent discovery that dispersion-managed
solitons have even superior properties than their conventional
counterparts. Today, it is clear that dispersion-managed
solitons, are the ultimate carriers for next generation
of fiber optical communication systems.
