Fiber coating

Low refractive index fiber inner coating refers to the coating of a material with a lower refractive index on the surface of the fiber to reduce the loss of optical signals in the fiber. Compared to ordinary optical fibers, low refractive index optical fibers have the following characteristics: 1. Reduce loss: Coating materials with low refractive index can effectively reduce the propagation loss of optical signals in optical fibers and improve transmission efficiency. 2. Enhance heat resistance: Low refractive index fiber coated trees usually have high heat resistance and can maintain stable transmission performance in high-temperature environments. 3. Can improve mechanical performance: can improve bending performance and bending strength 4. Adapting to high environmental conditions: Low refractive index coated resin can improve the weather resistance of optical fibers
