    • An optical fiber includes: a core at a center; a first cladding layer; a second cladding layer; and a third cladding layer. A maximum refractive index of the core is greater than any of maximum refractive indices of the first cladding layer, the second cladding layer, and the third cladding layer, and the maximum refractive index of the second cladding layer is smaller than any of the maximum refractive indices of the first and the third cladding layer. Additionally, a ratio of a2/a1 is not less than about 2.5 and not more than about 4.5, where a1 represents the radius of the core, and a2 represents the radius of an outer periphery of the first cladding layer, and a relative refractive index difference of the core with respect to a maximum refractive index of the third cladding layer is not less than 0.20% and not more than 0.70%.
    • 光纤包括:中心的芯; 第一包层; 第二覆层; 和第三覆层。 芯的最大折射率大于第一包层,第二包层和第三包层的最大折射率中的任何一个,并且第二包层的最大折射率小于任何最大折射率 第一和第三包层的指数。 此外,2×2 / a <1的比例不小于约2.5且不大于约4.5,其中1表示芯的半径,而2 表示第一包层的外周的半径,芯相对于第三包层的最大折射率的相对折射率差为0.20%以上且0.70%以下。
