摘要：
Lumped dispersion compensation is numerically investigated for 40-Gb/s return-to-zero differential phase-shift-keying transmission. Using pseudorandom binary sequence lengths up to 2(11) - 1, simulation results indicate that better long-distance transmission performance can be achieved using lumped dispersion compensation than using conventional periodic inline dispersion compensation. Improved performance is found to be a result of reduced nonlinear effects and the elimination of periodic accumulation of non linear effects. The lumped compensation scheme provides a simple, flexible, and potentially low-cost solution for transmission link design.
