Feasibility of densely dispersion managed soliton transmission at 160 Gb/s

We numerically demonstrate 160 Gb/s densely dispersion-managed soliton transmission in a single channel over 2000 km in the dispersion-flattened fibers in the presence of polarization mode dispersion and of large variation in group-velocity dispersion. The best performance is achieved by a proper design of the dispersion profile with possible minimum average dispersion, so that the soliton interactions are minimized.
