Recently, China Mobile held a press conference in Beijing and announced that the world's first self-developed 400G all-optical interprovincial backbone network has been officially commercialized. By the middle of the year, high-speed interconnection between the eight major hubs of "East and West" will be fully realized. By then, China Mobile will become The first 400G all-optical inter-provincial backbone network operator with the largest scale and widest coverage in the world. Li Huidi, deputy general manager of China Mobile, attended the press conference and delivered a speech.
Li Huidi said that China Mobile fulfills its responsibilities as a central enterprise, seizes the opportunities of the development of the times and network transformation, continuously strengthens the layout of new information infrastructure construction, optimizes and builds a "4+N+31+X" computing power layout system, strengthens computing power network, artificial intelligence Intelligent and other new generation information technology integration and innovation, took the lead in proposing the "Jiuzhou" computing power optical network evolution system, and centered on the "six optical and six pole" goal and vision, coordinated with the domestic industry chain, independently and independently overcome the three major technical difficulties of 400G, and realized key technologies and core The device is fully independent and independent, laying a solid foundation for the inter-computing intelligent connectivity capability of "optical and electronics connecting the east and west, and one network connecting nine states", promoting the development of computing power across regions and levels, and injecting new momentum into the development of the national digital economy.
The 400G all-optical interprovincial backbone network is a long-distance optical signal transmission network device that can connect edge, center and hub cluster computing power and is the connection hub of the computing power network. Through innovative breakthroughs in key technologies such as 400G QPSK high-performance encoding and decoding technology, C6T+L6T ultra-wide spectrum, and saturated optical power dynamic balance control, it provides ultra-large bandwidth, ultra-low latency, and ultra-high speed for hub cluster computing power integration and collaboration. Capacity, ultra-high security, ultra-high energy efficiency, ultra-high intelligent interconnection and other guarantees. Compared with the previous generation trunk network, the transmission bandwidth has been increased by 4 times, the network capacity exceeds 30PB, the inter-hub latency is less than 20ms, the latency of key active links has been reduced by 20%, the security capabilities have been fully upgraded, and the energy consumption per bit has been reduced by 65%. %, and the cost per bit is reduced by 20%.
The Central Economic Work Conference proposed that technological innovation should be used to promote industrial innovation, especially disruptive and cutting-edge technologies to spawn new industries, new models, and new drivers, and develop new qualitative productivity. The 400G all-optical inter-provincial backbone network will support the innovative cross-regional optimal allocation of production factors such as computing power and data, and support "Eastern data and west computing", "Eastern data and west storage", "Eastern data and west training", "Eastern data and west rendering", etc. The implementation of new applications will promote in-depth transformation and upgrading of the industry. Thanks to the blessing of computing power, applications such as speech recognition, smart factories, smart furniture, and autonomous driving will become more efficient and convenient.
