The core has a radius R1 in a range of 28 to 50 microns, a refractive index profile of a parabola shape with α being in a range of 1.9 to 2.2, and a maximum relative refractive index difference Δ1% max being in a range of 1.9% to 2.5%. The cladding includes an inner cladding and/or a trench cladding, and an outer cladding disposed from the inner to the outer in sequence. The radius R2 of the inner cladding is in a range of 28 to 55 microns, and the relative refractive index difference Δ2% is −0.1% to 0.1%.

Abstract: A fiber preform, including: a fiber core rod and an outer cladding layer. The ratio of the diameter of the fiber core rod to the diameter of the core layer thereof is 2.1-2.8. The fiber core rod and a small fluorine-doped quartz glass tube are melted to form a core rod assembly. The ratio of the diameter difference between the core rod assembly and the fiber core rod to the diameter of the core layer is 0.5-2.2. The relative refractive index difference of fluorine-doped quartz glass relative to purified quartz glass ΔF is −0.20% to −0.35%. The core rod assembly is arranged with a large purified quartz glass tube, or directly deposited with a SiO2 glass cladding layer. A ratio of an effective diameter of the fiber preform to the diameter of the core rod assembly is 2.0-5.6. Methods for manufacturing the preform and a fiber are also provided.
