a Calculated dispersion of optical fiber with 4 µm ~ 125 µm cladding diameter. The dispersion at 780 nm and 1030 nm reaches minimum values of -124.04 ps/nm·km and -41.44 ps/nm·km at 18 μm and 21 μm cladding diameters, respectively. b Calculated nonlinearity of optical fiber with 4 µm ~ 125 µm cladding diameter. The nonlinearity at 780 nm and 1030 nm reaches maximum values of 14.52 W⁻¹/km and 6.66 W⁻¹/km at 19 μm and 22 μm cladding diameters respectively, and reaches minimum values of 4.98 W⁻¹/km and 1.38 W⁻¹/km at 9 μm and 12 μm cladding diameters respectively
