[Ministry of Industry and Information Technology: Strengthen the research and development of ultra-high-speed and large-capacity optical transmission, optical access, and submarine cable optical communication technologies, and accelerate the research and development and application of new optical fiber technologies such as hollow core optical fibers] On September 7, the Ministry of Industry and Information Technology issued the "15th Five-Year Plan for the Development of the Information and Communications Industry." It mentioned that we should strengthen research on key core technologies. Strengthen innovation leadership, accelerate 6G core technology research and development, and continue to carry out 6G technology trials. Strengthen the research and development of ultra-high-speed and large-capacity optical transmission, optical access, and submarine cable optical communication technologies, accelerate the research and development and application of new optical fiber technologies such as hollow-core optical fibers, and carry out research on integrated application technologies in industries such as vehicle-mounted optical communications and industrial control optical networks. Strengthen data communication technology innovation and conquer technologies such as IP wide-area lossless transmission and stream-level load balancing. Promote the research and development of computing power transmission channel technologies such as computing and computing network resource sensing. Strengthen research on key satellite communications technologies such as efficient satellite-to-ground transmission, inter-satellite networking and routing. Accelerate the layout of cutting-edge technologies in cross-integration fields such as optoelectronic fusion, quantum encryption, and information communication network integration.
