The present invention generally provides optical signal transmission system having an optical signal source, at least one optical signal regenerator in series communication with the optical signal source via an optical signal communications medium, a dispersion module in series communication with the at least one optical signal regenerator via the optical signal communications medium, and a receiver in serial communication with the dispersion module via the optical signal communications medium. The dispersion compensation module inserts an amount of lumped dispersion into the system, which operates to improve the signal transmission characteristics.
