The stability of optical solitons amplified periodically by stimulated Raman scattering process in heavy fluoride fibers, is numerically studied for a range of parameters using computer simulation. An optimum single-mode fluoride fiber was used to design an all-optical soliton based optical fiber communication system. The value of the chromatic dispersion is 0.6 psec/nm/km with acceptable manufacturer tolerances. The length-bandwidth product is four times that of a soliton-based optical communication system using present day silica fibers. In this design we numerically justify why we neglect the higher order terms in the Taylor series expansion of the propagation constant around the pulse central frequency.
The single channel bandwidth-length product for bit error rate (BER) less than 10-9 is nearly 120,000 GHz.km. Typical amplification periods are in the range of 200-300 km; average soliton and pump power are in the range of milliwatts and hence well within the capability of semiconductor lasers.
