At present, industrial communication networks are facing new challenges. In the application fields of CNC machine tools and industrial robots, as well as semiconductor manufacturing, metallurgy, energy and other industries, due to the use of new production processes and production equipment, coupled with the complex and changeable industrial site environment, this puts forward extremely high requirements for industrial communication networks, such as high-precision multi-axis synchronization, large data volume and ultra-long distance high-precision transmission, and strong anti-interference ability. F5G uses optical fiber as a transmission medium, with the advantages of anti-interference, high reliability, strong real-time, low jitter, large bandwidth, etc., which naturally meets the extremely high demand for data communication in the implementation of intelligent manufacturing.

Under the guidance of intelligent manufacturing and digital transformation goals, SI and Huawei proposed an industrial light bus solution based on F5G technology. Together with Huazhong University of Science and Technology, Central South University, Shenzhen Zhengsports Technology Co., LTD., Wuhan Maixin Electrical Technology Co., LTD., Changzhou Luoyuan Intelligent Technology Co., LTD., Shanghai Bochu Electronic Technology Co., LTD., Shenzhen Huacheng Industrial Control Co., Ltd. and other partners, launched joint innovation and application in multiple scenarios and industries in the manufacturing industry. The industrial optical bus uses all-optical communication technology to connect the industrial site production factors, which can not only make the data flow of enterprises smoother, ensure the efficient and comprehensive carrying of business data, production data and control data, but also ensure the bus safety, convenience and ease of use, and provide an overall solution for optical bus interconnection in different industrial production scenarios. At the same time, it promotes the accelerated popularization of machine vision inspection, accurate remote control, on-site auxiliary assembly, unmanned patrol security and other applications, which has significantly improved the production level of enterprises, and its advantages have been widely recognized by the industry.

In the future, the Institute and Huawei will cooperate with more partners to deeply cooperate with various industries and industrial chains, explore more and richer F5G industrial manufacturing application scenarios, and make continuous contributions to the high-quality development of intelligent manufacturing in China.
