To improve the transmission capacity of optical communication, the research goal of full-band large effective area optical fibers is proposed by analyzing the advantages and limitations of G.652.D and G.654.E optical fibers, as well as typical application scenarios of optical fiber transmission. Based on the hypothetical inference of fiber quality factor and compatibility, thepower exponent g of the gradient refractive index distribution of the full band large effective area fiber is analyzed and calculatedfrom formulas such as fiber refractive index distribution, normalized frequency of the fiber, and local aperture. The solution ideasfor the attenuation and bending performance of the new fiber are discussed, which expands new directions for the development ofnew fibers that can be compatible with the performance of G.652.D and G.654.E.
