Stable propagation of solitons in strongly dispersion-managed unequal-length optical fiber link with loss

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 solito n propagate 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 o f article, we give two types of link with peak power 2 and 8 mW, With an in put pulse train consisting of 32 bits in return-to-zero (RZ) format, numeri cal simulation has been done, We find that soliton can stably propagate thr ough these optical fiber link constructed by ten unequal-length unit with a data rate of 13.33 Gb/s.
