In previous papers we have shown that it is possible to generate high-repetition-rate GHz-THz trains of uninteracting solitons from a dual-frequency signal by using a weak amplification of the signal in fibers. The length of the fiber necessary for the soliton train generation grows quadratically with increase of the generated solitons pulse width. The fiber length varies from 10-300 m for the soliton pulsewidth of about 100 fsec to thousands of km for the case of relatively long about 50 psec solitons. At the present state of fiber optics technology there are reasons that relatively long solitons are required for ultra long distance transmission. But the discussed method requires too long fibers for generation of such solitons.
