Computing Power Networking and Optical Technology Development Forum(Finished)

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.

Gigabit Optical Access Broadband Development Forum(Finished)

With the gradual improvement of the global gigabit broadband urban application scenario, more and more users demand gigabit. According to Omdia, the number of gigabit users worldwide will exceed 150 million by the end of 2022 and 400 million by 2027. With the rapid development of gigabit users, the optical communication market has an increasing demand for high-speed broadband large-capacity transmission, more flexible network deployment, high efficiency and energy saving products with high link budget. At the same time, the gigabit intelligent optical network needs to transform from the "gigabit" connection capacity of bandwidth to the "gigabit" service capacity of bandwidth + experience, to meet the needs of the development of gigabit services in the digital age. At present, the gigabit optical access network uses 10G GPON+ Gigabit gateway +WiFi6 technology to fully realize the capability of "end-to-end gigabit fixed network". With the experience dividend of scene broadband, the market value of PON+ thousand lines and all industries is displayed. In the future, the PON network will continue to evolve to 50G, and the development of 50G PON technology needs to be further standardized. Facing the speed upgrade of PON network, the 50G PON optical module industry is still in the initial stage. How can the PON system improve the low-delay technology to achieve multi-point collaborative networking, and how to control the intelligent gateway to improve the network experience?

Data Center Optical Interconnection Evolution Trends Forum(Finished)

In 2023, ChatGPT became popular on the global network. The prosperity of AI industry is in urgent need of strong data center computing power to support, and high-speed digital and optical communication technology, as the key technologies to achieve stronger computing power of data centers, is facing increasingly urgent challenges. At present, the rapid development of the application scenario of large computing power will accelerate the evolution of optical modules from 800G to 1.6T. At the 1.6T speed, the integration degree and power consumption of traditional pluggable optical modules will become more prominent. Low power consumption and miniaturization become the key demands of 800G and 1.6T optical modules. Linear drive pluggable solution has also become the focus of attention in the industry. With the rapid development of cloud data centers and the continuous rise of traffic, higher demands are put forward for high-speed transmission technology of data centers from the level of network, server, switch equipment capacity, chip and module. New data center switch technologies such as CPO/NPO are also expected to accelerate their application in the future. The evolution of switching chip capacity, optical module technology, the openness and decoupling of optical network, the establishment of data center industry standard and the collaboration of the industry still need to be discussed.

Optoelectronic Chip Design, Manufacturing and Packaging Technology Forum(Finished)

Under the continuous promotion of new high broadband services and applications such as 5G Internet, cloud computing and big data, the evolution and upgrading of network business traffic in the telecom market of operators and optical interconnection networks of data centers all require upgrading of the rate requirements, design process, packaging form and performance technology of the optoelectronic chips used in them. At present, optoelectronic chips are accelerating into the post-Moore era, during which silicon optical chips combine the advantages of photons and electrons, break through the limitations of Moore's Law, and meet the explosive computing power needs brought by AI industry and cloud computing. Silicon optical chips are expected to carry high-speed data transmission in large data centers in the next three years. In 2023, with the increasing demand for 400G/800G/1.6T optical modules, the combination of thin film lithium niobate chip and silicon optical process has become the technical direction of the industry. At the same time, as a microprocessor that can process all kinds of digital signals quickly and in real time, DSP chip has gradually penetrated into communication, computer, consumer electronics and other fields, especially in the digital age, DSP chip market scale has gradually grown. However, DSP has always been a "bottleneck" problem restricting the development of national optical communication industry. Due to the relatively closed ecology of DSP chip industry and high intellectual property barriers, there has not been a mature domestic program that can directly replace it. At present, the market share of domestic DSP chip manufacturers is still small, but the downstream market with strong demand is calling for domestic chip products with good cost performance and independent intellectual property rights. It is urgent to break the foreign technology monopoly and improve the self-supply rate of domestic DSP chip.
