On June 26, GLJ Research reported that Advanced Fiber Resources (300620.SZ) stated on the investor interaction platform that after years of development, the company has independent product design and development capabilities. The company's product design level, quality control, and performance indicators can achieve advanced levels in the industry, and has established a comprehensive product series. It can provide customers with a one-stop solution for fiber optic component matching. Among them, several high-power fiber optic laser components and optical communication components represent a relatively high level in the industry: The optical fiber feeding product of the submarine optical network developed by the company is the first in China and solved the problem of import substitution. It has been successfully applied to the current industry's most advanced 16-fiber-to-sea optical cable system. The company has mass-produced high-reliability passive optical components for submarine optical networks, and is one of the few manufacturers in the world that can provide such components; the company's independently developed high-power isolators with high heat lens effect elimination and high reliability As the core device of high-power fiber optic lasers, it has been widely used by well-known fiber optic laser manufacturers at home and abroad; the company's independently developed high-power fiber optic grating products have basically replaced imported products; the company's developed special wavelength fiber optic components such as 2μm devices, visible lights (400-760nm) devices, etc. can be used in fiber optic lasers, medical devices and other fields, fully demonstrating the company's customization capabilities; in the field of lithium niobate modulator chips, the company has core technologies including chip design, chip processes, packaging, and testing, and has the key ability to develop thin film lithium niobate modulator chips and devices with a speed of up to 800Gbps or more.
