摘　　要：为提升光通信传输容量,通过分析G.652.D、G.654.E光纤的优势和局限性,以及光纤传输的典型应用场景,提出全波段大有效面积光纤的研究目标。基于光纤品质因数和兼容性的假设性推断,从光纤折射率分布、光纤的归一化频率、局部孔径等公式分析计算得出全波段大有效面积光纤的渐变折射率分布幂指数g,并探讨新型光纤的衰减、弯曲性能的解决思路,为实现能够兼容G.652.D、G.654.E光纤性能的新型光纤开发拓展了新的方向。To improve the transmission capacity of optical communication,the research goal of full-band large effective area opti-cal fibers is proposed by analyzing the advantages and limitations of G.652.D and G.654.E optical fibers,as well as typical appli-cation scenarios of optical fiber transmission.Based on the hypothetical inference of fiber quality factor and compatibility,the power exponent of the gradient refractive index distribution of the full band large effective area fiber is analyzed and calculated from formulas such as fiber refractive index distribution,normalized frequency of the fiber,and local aperture.The solution ideas for the attenuation and bending performance of the new fiber are discussed,which expands new directions for the development of new fibers that can be compatible with the performance of G.652.D and G.654.E.
