In 2023, driven by policy, demand and technology, the integration of computing network will continue to develop in depth. Integrated computing base, intelligent computing scheduling, green sustainable computing, and the construction of 400G all-optical network will become the key words for the development of computing network. The national "count the East and count the West" project and the popularity of ChatGPT this year have further boosted the demand for large computing power, linking data, computing power and network closely. Not only the computing network needs to have super capacity, but also the optical network needs to provide high-quality connectivity and super capacity. As an important component of information infrastructure and a key bearer base, optical network can meet the demands of computing power on transmission bandwidth, capacity and low delay.
Today, the infrastructure construction of computing network drives the deep integration of computing, cloud and optical network, enabling the digital transformation of all walks of life. Subsequently, the optical transmission network is also evolving in a diversified way, such as ultra-high speed and large capacity, flexible and open, collaborative intelligent management and control. From the perspective of high-speed transmission technology, 400G has been opened for commercial use, and 800G is getting more attention. 400G QPSK and C6T+L6T technology are a 10-year intergenerational technology under the large-capacity and ultra-long distance backbone network. How to further improve the transmission capacity based on spectrum extension has aroused the attention of the industry.
With the maturity and innovation of related technologies, optical network is also promoting the transformation of network from infrastructure network to business network through the reconstruction of network architecture, so as to better serve the digital economy. In the face of development opportunities such as new infrastructure construction and industrial digital transformation, our optical communication industry is still facing multiple challenges in the evolution of network intelligence, integrated development of computer and network, green and low-carbon, application scenario expansion, and so on.

In this context, CIOE will invite the three major domestic operators and system equipment vendors, head optical chip/module vendors to hold a forum on the development of arithmetic network and optical technology, focusing on the discussion of high-speed transmission technology topics of super capacity, open decoupling, cooperative networking and intelligent control.
