    • A graded index multimode optical fiber comprising: (a) a silica core doped with germania, and at least one co-dopant, comprising one of P2O5 or F or B2O3, the core extending to outermost core radius, r1 and having a dual alpha, α1; (b) a low index inner cladding surrounding the core and off-set from said core; (c) an outer cladding surrounding and in contact with the inner cladding, such that at least the region of the inner cladding off-set from said core has a lower refractive index than the outer cladding. The center germania concentration at the centerline, CGe1, is greater than or equal to 0, and an outermost germania concentration in the core CGe2, at r1 is greater than or equal to 0. The core has a center co-dopant concentration at the centerline, Cc-d1, greater than or equal to 0, and an outermost co-dopant concentration Cc-d2, at r1, wherein Cc-d2 is greater than or equal to 0.
    • 一种分级折射率多模光纤,包括:(a)掺杂有氧化锗的二氧化硅芯,以及包含P2O5或F或B2O3之一的至少一种共掺杂物,所述芯延伸到最外芯半径r1并具有双重α, alpha1; (b)围绕所述芯并偏离所述芯的低折射率内包层; (c)包围并与内包层接触的外包层,使得至少从所述芯偏离的内包层的区域具有比外包层更低的折射率。 中心线CGe1处的中心锗浓度大于或等于0,核心CGe2在r1处的最外面的锗浓度大于或等于0.核心在中心线处具有中心共掺杂剂浓度 ,Cc-d1,大于或等于0,最外侧辅助掺杂浓度Cc-d2在r1处,其中Cc-d2大于或等于0。
