摘要
提出了一种有效的简化数值算法模拟反向多波抽运拉曼放大器的传输性能,考虑了包括色散、非线性等效应,以及放大器放大自发发射噪声对多信道宽带分布拉曼放大系统性能的影响,并且具有足够的精度。作为模型的应用,模拟了一个64×10 Gb/s的拉曼宽带级联放大系统的传输特性,比较了不同入纤功率对接收性能的影响,得到了一些有益的结论。
Abstract
A simple and novel numerical algorithm is proposed to simulate the transmission performance of a counter multiwave pumped Raman amplifier. In this model the system impact caused by dispersion, nonlinear and ASE is considered, and the results have satisfying accuracy. As an application, a 64×10 Gb/s Raman broadband multi stage system was simulated, and the influence of different input signal power level was compared. Some helpful conclusions are achieved.
