Abstract

A novel design of densely dispersion-managed optical fiber transmission systems with decreasing average dispersion and decreasing local dispersion (dual-decreasing DDM) is proposed. The system is characterized by gradually decreasing not only local dispersion in each fiber segment, but also average dispersion in every dispersion compensation cell. When an optical pulse propagates along an optical fiber link, transmission loss weakens the Kerr effect to break the balance between dispersion and nonlinearity. To deal with the problem, dispersion parameters in a densely dispersion-managed system are made to vary gradually to counterbalance the nonlinearity. This novel approach has a number of advantages over ordinary densely dispersion-managed (DDM) soliton transmission systems, including allowing higher pulse power and reduction of optical pulse broadening, hence there is less interaction between neighboring pulses. Simulation results indicate that the dual-decreasing DDM has better propagation performance in comparison with the ordinary DDM in a high-speed optical communication system.
