Problems solved by technology

With the gradual thinning of optical fibers, the requirements for operating temperature are becoming wider and wider, and the requirements for optical fiber coatings are also getting higher and higher. After using the existing optical fiber coatings to prepare thin-diameter optical fibers, the optical properties will decrease (such as attenuation, crosstalk, etc.) etc.), the decrease of the dynamic fatigue parameter Nd value, etc., so that the overall performance of the optical fiber is significantly reduced
