Hi Vikas
As ranjeet has mentioned rightly that soliton based optical fiber communication systems are more suitable for long haul communication because of their very high information carrying capacity and repeater less transmission.Soliton pulses does not affected(by dispersion) after long distance communication. It is true that the fact that solitons are spatially localized and propagate with (little to) no deformation makes them the carriers of choice for modern optical communication, as they can be used to encode a bit in a small amount of space through the presence or absence of the pulse in a designated temporal window.
For dispersion compensation you can easily use fiber bragg grating. I will try to attach few links of some papers which have used fiber bragg grating for dispersion compensation.
Thanks
