Paper Abstract

The single mode fibers with chromatic dispersion varying along the length are an attractive medium for nonlinear optics. For optical soliton, a small dispersion varying perturbs soliton in the same way as an amplification or loss. Such fibers allow to realize both the regime of effective amplification and the effective compression of optical solitons. The method to draw fibers varying along the length from standard preform had been developed. The length of fiber with varying dispersion may be in the range from several meters to several kilometers. The dispersion deviation from the prearranged value is less than 0.1ps/nm/km. In accordance with modern theoretical underground it is possible to develop the DDF (dispersion decreasing fiber) with advanced dispersion profile to reduce radically the timing jitter and extend the transmission distance. In addition, one is able to design the dispersion profile of dispersion varying fiber (DVF) in such way that it would be possible to apply one and the same DVF both in linear WDM and soliton communication systems.
