With the comprehensive launch of the digital economy era, computing power, as a new form of productivity, is injecting new momentum into the digital transformation of various industries and becoming an important driving force for high-quality economic and social development. In 2023, the AI wave sparked by OpenAI swept the globe, and in 2024, China Mobile officially commercialized the world's first 400G all-optical inter-provincial backbone network, ushering in a new era of optical transport networks with the large-scale commercialization of 400G. The concept of computing power has further gained popularity, and the demand for computing power has exploded rapidly. The large-scale commercialization of 400G OTN will further drive the development of optical communication technology, satisfy the ever-growing demand for data transmission, enhance network performance and security, and is an inevitable choice for the next-generation all-optical backbone transport network.

This event will explore the technological development trends and application scenarios of 400G optical transport networks. Through strengthening technological research and development, promoting industrial upgrading, optimizing resource allocation, and other means, we aim to achieve sustainable development in the optical communication industry.
