摘要：
Based on the improved coupled power equations, a signal-to-noise ratio (SNR) calculation model is proposed for multi-core fiber C + L band SDM-WDM systems. Based on this model, the effects of inter-core crosstalk (ICXT) and Stimulated Raman Scattering (SRS) on the transmission performance is investigated in the MCF C + L band WDM system. The results show that both SRS and ICXT will influence the system performance significantly. Furthermore, four strategies for optimizing the channel incident power are investigated for the SRS impact. The output power flattening strategy is found to perform well in terms of system capacity and optimization efficiency.
