In this paper, a 16-channel 40 Gb/s wave division multiplexing lightwave system is simulated using OptiSystem version 14 and optimized. This paper proposes a Pareto optimization and particle swarm optimization algorithms to find optimum launch power for minimum bit error rate (BER). However, simulation results show that the proposed algorithms proved to be a good solution and take considerable computational time to converge and reach global optimum. It is concluded that return-to-zero modulation format has higher-quality factor, lower BER, and lower distortion and it is less affected by the fiber nonlinearity.

使用最佳调制格式的WDM光波系统的设计和性能优化

在本文中，使用OptiSystem版本14对16通道40 Gb / s波分复用光波系统进行了仿真并进行了优化。本文提出了帕累托（Pareto）优化和粒子群优化算法，以找到最小误码率（BER）的最佳发射功率。然而，仿真结果表明，所提出的算法是一种很好的解决方案，需要花费大量的计算时间才能收敛并达到全局最优。结论是归零调制格式具有较高的品质因数，较低的BER和较低的失真，并且受光纤非线性的影响较小。
