摘要
We propose a modified soliton control method for a strongly dispersion managed line, which employs a highly non-linear fiber in addition to conventional inline synchronous modulation. This method enables us to transmit a 40-Gb/s return-to-zero signal over 20 000 km using a dispersion managed line composed of a standard (nondispersion shifted) fiber and dispersion compensation. Optimizing the length of the highly nonlinear fiber greatly increases the power margin of the transmitted optical power.
