本文从数值建模仿真的角度探讨了在不同调制格式下,色散、非线性效应、光放大器噪声以 及光源线宽稳定性等对于40Gbit/s信号传输距离的影响,同时分析了FEC技术与40Gbit/s信号传输距离 之间的关系。
This paper discusses the influence of dispersion, nonlinearity, optical amplifier noise and linewidth stability on the 40Gbit / s signal transmission distance under different modulation formats from the perspective of numerical modeling and simulation, and analyzes the relationship between FEC and 40Gbit / s signal transmission distance between the relationship.
