摘　　要：400G及以上光传输系统对光纤链路的OSNR损耗、非线性容限等性能提出了更高的要求,超低损耗大有效面积光纤成为下一代光纤技术发展的主流方向。从下一代光纤技术发展方向分析出发,介绍了超低损耗大有效面积光纤的制备原理和关键技术,并对比了采用U3LA超低损耗大有效面积光纤和普通的G.652光纤链路的超100G光传输系统性能。实验结果表明,采用U3LA超低损耗大有效面积光纤可以提升超100G光传输信号的传输性能和传输距离超50%。400 G and beyond 400 G optical transmission systems have put forward higher requirements for the performance of OSNR loss and nonlinear tolerance of optical fiber links,which makes ULL LEAF fibers become the mainstream of technology development of next generation optical fibers. Based on the analysis of the development trend of the next generation optical fiber technology,it introduces the principles and the key techniques in ULL LEAF fibers manufacturing. The performance of the U3 LA ULL LEAF fibers and the general G.652 fibers in beyond 100 G optical transmission system is compared. And the experimental results indicate that it can increase the transmission performance and distance in beyond 100 G optical systems by at least 50% by using ULL LEAF fibers.
