Abstract

The application discloses an anti-light-induced-loss short-wavelength low-attenuation single-mode optical fiber and a preparation method thereof, and belongs to the technical field of special optical fibers. The anti-light-induced-loss short-wavelength low-attenuation single-mode optical fiber is prepared by optimizing the structure of the optical fiber, forming a core layer containing a Gaussian distribution core and a step distribution core, and optimizing the proportion of SiO2 / F / Cl elements in each layer and the combination of the relative refractive index difference of each layer. The anti-light-induced-loss short-wavelength low-attenuation single-mode optical fiber can be accurately obtained. The preparation process of the anti-light-induced-loss short-wavelength low-attenuation single-mode optical fiber is simple to control, can meet the application of the single-mode optical fiber in the visible blue-green light band, reduces Si-O bond defects and non-bridge oxygen defects in the optical fiber, meets the application requirements of the anti-light-induced-loss, short-wavelength and low-attenuation single-mode optical fiber, prolongs the service life of the optical fiber, and improves the service performance of the single-mode optical fiber.
