This article systematically explains how optical modules build an efficient and stable interconnection system for intelligent computing centers, covering core application scenarios, deployment key points, network adaptation strategies, and implementation processes. Artificial intelligence (AI) refers to the intelligence displayed by the machine, that is, the computer simulates the functions of the human brain based on big data. Such as reasoning, visual recognition, semantic understanding, learning ability, planning and decision-making ability. Using advanced optical modules boosts AI system speed and bandwidth, helping handle large data loads with low delay and high efficiency. Optical modules. The routed optical networking solution can enable scale by converging mobile and fixed, voice and private line trafic onto a single converged internet protocol (IP) and optical network. SPs understand that they must transform their transport networks to prepare for the 5G. In Feb. 2023, the State Council issued the "Overall Layout Plan for Digital China Construction. ” It proposes six key tasks,including enhancing the efficient. Optical Module and DCI by Application (Communication Service Provider, Internet Content and Carrier Neutral Provider, Government/Research and Education, Other), by Types (Optical Transport Network, Data Center Core Network, WAN), by North America (United States, Canada, Mexico), by South America.
