Using average approximation, we obtained a phase plane evolution picture of soliton propagated in strongly dispersion-managed optical fiber link with loss. After analyzed this picture, we proposed a new picture to keep soliton propagation stably in this system. Stable propagation parameters are given and twenty points we are interested in are selected. Using these parameters, we can construct any type of optical fiber link. Considering the length of article, we give two types of link with peak power 2 and 8 mW. With an input pulse train consisting of 32 bits in return-to-zero (RZ) format, numerical simulation has been done. We find that soliton can stably propagate through these optical fiber link constructed by ten unequal-length unit with a data rate of 13.33 Gb/s.
