Optical communication equipment. Optical communication equipment includes optical fiber optic cable, optical device and optical communication equipment. The industry of optical fiber optic cable and optical communication equipment in China has developed mature, with high market concentration and stable competition pattern. The independent R & D and innovation ability of leading enterprises has been continuously improved, which has led to the continuous improvement of barriers to entry of industry, and further concentrated market share to large enterprises. In the field of optical devices, China is the largest optical device manufacturer in the world, but it still relies on import because of its insufficient technical strength in high-end chips and core devices.
