In the past decade, China's fiber optic preform industry has deeply integrated into traditional manufacturing, energy, transportation, and information infrastructure fields, achieving a structural transition from 'material supply' to 'system empowerment'. In terms of technological integration, enterprises such as Changfei Fiber Optic and Zhongtian Technology have broken through the three core processes of PCVD, OVD, and VAD, with a self-sufficiency rate of over 90% for prefabricated rods and a single rod drawing length of over 10000 kilometers, supporting the construction of 5G base stations, east-west computing backbone networks, and submarine optical cables; At the level of intelligent manufacturing, Hengtong Fiber Optic has built the world's first 'lighthouse factory' for optical communication, achieving full process closed-loop control through AI simulation and digital twin, increasing production efficiency by 66% and reducing unit costs by 21%; In terms of material collaboration, upstream raw materials such as high-purity quartz and erbium oxide have been domestically replaced, and the supply chain is independently controllable. Companies such as Xinyi Fengtai Quartz Products and Foshan Daishi Chemical provide stable high-purity raw materials for prefabricated bars; In the application extension, optical fibers derived from prefabricated rods are widely used for online monitoring of smart grids, health sensing of high-speed rail structures, and early warning of oil and gas pipeline leaks, promoting the traditional industry to shift from 'passive operation and maintenance' to 'active perception'. The Ministry of Industry and Information Technology's '14th Five Year Plan' for the development of the information and communication industry clearly lists high end optical communication materials as a key research direction, and the National Information Optoelectronics Innovation Center accelerates the research and development of hollow core optical fibers. In 2026, Changfei will release HollowBand ® Hollow fiber optic cable, with attenuation as low as 0.04dB/km, reduces latency by 31%, ushering in a new era of ultra-low latency communication.
