OPTICAL FIBER RAW MATERIAL COMPOSITION, OPTICAL FIBER, AND OPTICAL FIBER PRODUCT

This application relates to the field of communication technologies, and discloses an optical fiber raw material composition, an optical fiber, and an optical fiber product. The optical fiber raw material composition includes components of the following molar percentages: AlF3 10%-50%, BaF2 3%-20%, CaF2 3%-20%, YF3 1%-15%, SrF2 3%-20%, MgF2 3%-20%, and TeO2 1%-35%. The optical fiber raw material composition can not only be used to prepare optical fiber cladding, but also be used to prepare an erbium-doped fiber core in collaboration with an erbium ion, so that a prepared optical fiber has a wide emission cross section and a strong anti-deliquescence function, and can implement a low-loss splice with the silicon fiber. The optical fiber prepared by using the optical fiber raw material composition provided in this disclosure can be used in aspects such as a mid-infrared band transmission optical fiber, an optical fiber amplifier, a fiber laser, and an optical fiber sensor.
