摘要： A single mode fiber having a core, an inner cladding, a depressed cladding, and an outer cladding composed of pure silica glass. The core is surrounded in sequence with the inner cladding and the depressed cladding. The core has silica glass doped with germanium and fluorine, with a diameter (a) of 8.0-8.8 μm, a relative refractive index difference (Δ1) of 0.35-0.38%, and the contribution of fluoride (ΔF) is −0.09±0.02%. The inner cladding has silica glass doped with germanium and fluorine, with a diameter (b) of 18-21 μm and a relative refractive index difference (Δ2) of 0±0.02%. The depressed cladding has silica glass doped with fluorine, with a diameter (c) of 26-36 μm and a relative refractive index difference (Δ32) at the external interface thereof is between −0.22 and −0.35%, and a relative refractive index difference (Δ31) at the internal interface thereof is between −0.20 and −0.35%, and Δ32≦Δ31. The fiber has a good bending resistance, good mechanical properties, and extended service lifetime, and prevents the additional stresses generated by bending from passing on to the core, thereby reducing attenuation.

摘要： A multimode fiber including a core and a cladding. The core has a radius (R1) of 24-26 μm, the refractive index profile thereof is a parabola, and the maximum relative refractive index difference (Δ1) is 0.9-1.1%. The cladding surrounds the core and includes from inside to outside an inner cladding, a middle cladding, and an outer cladding; a radius (R2) of the inner cladding is 1.04-1.6 times that of the core, and a relative refractive index difference (Δ2) thereof is −0.01-0.01%; the middle cladding is a graded refractive index cladding whose radius (R3) is 1.06-1.8 times that of the core, and a relative refractive index difference thereof is decreased from Δ2 to Δ4; and a radius (R4) of the outer cladding is 2.38-2.63 times that of the core, and a relative refractive index difference (Δ4) thereof is between −0.20 and −0.40%. The invention reduces the additional bending loss of the fiber, improves the bending resistance and mechanical properties, basically eliminates the internal stress, and ensures the service life even working for a long term under the condition of low radius. The method for producing the fiber is simple, effective, and suitable for mass production.
