摘　　要：针对多芯光纤暂无工程实际应用数据的情况,本文首先结合多芯光纤应用方案及OTN传输系统中的光信噪比指标,理论分析多芯光纤应用的可行性,然后结合理论分析结果,提出了多芯光纤制造及多芯光纤在工程设计时的优化建议,最后给出了多芯光纤在干线和城域网骨干网络中应用时的熔接损耗值不应大于0.22 dB。多芯光纤应用分析结果可为后期多芯光纤的研发及工程建设提供参考。Aiming at the lack of engineering practical application data of multi-core optical fiber,this paper firstly combines the application scheme of multi-core fiber and the optical signal noise ratio index in OTN transmission system,the feasibility of multi-core fiber application is analyzed theoretically,then combine the theoretical analysis results,the optimization suggestions for the manufacture of multi-core fi ber and the engineering design of multi-core fi ber are put forward,fi nally,the fusion loss of multi-core fi ber should not be greater than 0.22 dB when it is used in trunk and metropolitan area network.The results of multi-core fi ber application analysis can provide reference for the development and engineering construction of multi-core fi ber in the later stage.
