Latest Patents
Fanghai Zhang holds a patent for a "Multi-mode bending-resistant fiber and production method thereof." This invention features a multimode fiber that includes a core and a cladding. The core has a radius (R) of 24-26 µm, with a parabolic refractive index profile and a maximum relative refractive index difference (Δ1) of 0.9-1.1%. The cladding surrounds the core and consists of an inner cladding, a middle cladding, and an outer cladding. The inner cladding has a radius (R) that is 1.04-1.6 times that of the core, with a relative refractive index difference (Δ2) ranging from -0.01 to 0.01%. The middle cladding is a graded refractive index cladding, with a radius (R) that is 1.06-1.8 times that of the core, and a relative refractive index difference that decreases from Δ2 to Δ4. The outer cladding has a radius (R) that is 2.38-2.63 times that of the core, with a relative refractive index difference (Δ4) between -0.20 and -0.40%. This invention effectively reduces additional bending loss, enhances bending resistance and mechanical properties, eliminates internal stress, and ensures a long service life even under low radius conditions. The production method for this fiber is simple, effective, and suitable for mass production.
