Energy enhancement of dispersion managed soliton transmission system using mostly normal dispersion fiber

The dispersion managed soliton transmission system using mostly normal dispersion fiber is investigated. It is shown that, with the same net anomalous dispersion, the optimum energy enhancement is larger for the system using mostly normal dispersion fiber than the system using mostly anomalous dispersion fiber. The allowed transmission distance for the system using mostly normal dispersion fiber is longer than those using mostly anomalous dispersion fiber.
