Optical Fiber


High purity quartz sand used in optical fibers represents the highest purity requirements and cutting-edge technological level in the field of high-purity quartz materials. It is the core raw material for manufacturing optical fiber preforms, and its purity, impurity control, and physical properties directly determine the transmission efficiency, signal loss, and long-term reliability of optical fibers. Our company produces high-purity quartz sand with a purity of 4N8-5N, uniform particle size (100-150 μ m), U/Th element content below 0.5 ppb, and hydroxyl content below 1 ppm, ensuring low loss transmission of optical signals. Some products have passed strict testing by well-known fiber optic companies such as Jiuzhi Optoelectronics.
