In recent years, the rapid development of the Internet and cloud computing has given birth to the construction of ultra-large-scale data centers. Driven by technologies and services such as artificial intelligence, big data, machine learning, AR, and VR, the data center's demand for network bandwidth continues to accelerate.Although the Moore's Law of CPU has entered its twilight years, the above new technologies and new services are booming. The drive for the iterative capacity of data center network switching chips still maintains a trend of doubling approximately every two years. Cloud computing improves efficiency through technology and scale, and provides stable, low-cost, and secure services through elastic computing. It has strong demands for the horizontal scalability of network architecture, technological dividends brought by technological iterations, and cost reduction. At the same time, with the evolution of converged and hyper-converged infrastructure, the function of the network is no longer just to provide connections, the network will become an extension of computer I/O, and ultra-high bandwidth and ultra-low latency networks are connecting local storage and networking. The boundaries of storage have become blurred. In short, elastic scalability, high availability, and low latency are the core requirements of large-scale data center networks.
As the base and cornerstone of the network architecture, in the process of data center physical network links evolving from 1000Mbps twisted pair to today's 400Gbps optical interconnection, the technical challenges of physical network links are increasing with the rapid increase of SerDes rate At the same time, the high stability of physical network links is also subject to the strong demands and challenges of high-availability, low-latency and even lossless networks as mentioned above. At the same time, the challenges to deployment efficiency and supply costs are also increasing. Physical network interconnection technologies such as high-speed passive copper cables, high-speed active copper cables, AOCs, and optical modules provide different solutions in different business scenarios and deployment environments, but in the future development trend, they still meet A series of challenges such as more diverse scenarios and tighter link budgets.
The White Paper on High-speed Copper Cable Technology for Next-Generation Data Centers focuses on high-speed copper cables, integrating the upstream technology and downstream application requirements of the entire ecological chain, and provides an industrial chain in the field of high-speed copper cables for domestic data center physical networks from demand, application to A more comprehensive reference of technical solutions. In terms of content, the white paper covers the application status and future development direction of high-speed copper cables in China's large data centers, to key technologies and industrial ecology of high-speed copper cables, and organizes the technical specifications and actual conditions of high-speed copper cables for the next-generation 56G-PAM4 rate. Constraints, test results and application guidelines are designed to help the entire ecological chain improve competitiveness in the design, manufacturing, application, and innovation of high-speed copper cables from the basic level, and contribute to the "new infrastructure" in this subdivision. The white paper was compiled by Alibaba, Tencent, Luxshare Precision, Zhejiang Zhaolong Interconnection and other units.
ODCC has always paid attention to the development of data center technology and industry, and has jointly compiled this white paper with related units, and has carried out a detailed review of the current status of data center networks, requirements and key technologies of high-speed copper cables, test results, development trends, etc., in order to further promote The development of data center network technology and related ecology.
