摘　　要：5G时代的业务需求给光承载网带来了新挑战,WDM传输系统已逐步向400G演进升级。2SC-PM-16QAM作为目前业界成熟的400G光调制技术,其高OSNR容限导致的传输距离缩短为主要应用限制。超低损耗G.652和大有效面积G.654的新型光纤可以显著改进系统性能,提升400G系统的传输距离。The requirement of 5 G mobile communication network brings new challenges to optical bearer network. WDM transmission system has gradually evolved to 400 G. 2 SC-PM-16 QAM is the most generalized 400 G optical transmission method in the industry,which is limited in the transmission distance caused by higher OSNR tolerance. Ultra low loss G.652 fiber and large effective area G.654 fiber can improve the performance of 400 G transmission systems. It is expected to enhance the transmission distance of 400 G optical transmission system.
