The World's First 400G All-Optical Interprovincial Backbone Network

On March 8, China Mobile announced that the world's first self-developed 400G all-optical interprovincial backbone network was officially commercialized. By the middle of the year, high-speed interconnection among the eight major hubs of "East and West" will be fully realized. By then, China Mobile will become the world's largest network. , the first 400G all-optical inter-provincial backbone network operator with the widest coverage.

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 code, C6T+L6T ultra-wide spectrum, and saturated optical power dynamic balance control, it provides ultra-large bandwidth, ultra-low latency, and ultra-high capacity for hub cluster computing power integration and collaboration. , 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 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 promote the 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.
