Abstract  By using the perturhation theory and small-amplitude approximation with the self-induced Raman effect and the loss as well as gain of the fiber taken into account, the transmission properties of solitons in the nomal dispersion region near the zero-group-dispersion wavelength are analytically investigated in this paper. The result shows that not only the small-amplitude dark soliton but also the small-amplitude bright soliton may exist in the normal dispersion region near the zero-group-dispersion point. Their stabilities depend on the propagating direction and the region in which they are situated in the parameter-space. The conversion between bright and dark solitons may be realized by controlling the relative intensities of gain and loss along the fiber. This may be applied to the logic or arithmetic devices in the integrated optical circuit.
