Accelerate 6G deployment, 800G optical modules may become the main force

The world's highest real-time transmission record of terahertz wireless communication. Compared with 5G, the communication rate achieved is up to 10 to 20 times higher. As the core of carrying network traffic, optical module, 800G optical module has naturally become the latest target pursued by the optical communication industry. This article, ETU-LINK, will take you to understand.

The 800G optical module is the standard configuration of the latest generation of optical transmission systems and has huge market potential. According to the forecast of a market research organization in the industry, starting from 2022, 800G optical modules will gradually increase. It is expected that sales of 400G optical modules will exceed 400G by 2024, and the market size will reach 7 billion US dollars. As early as 2018, my country began to study 6G; in 2019, 6G technology work was officially launched to realize voice, SMS, high-definition video, Internet of Things, and air-space-ground integrated networks.

Two schemes are first defined in the 800G pluggable MSA, namely 800G-SR8 and 800G-FR4. In the SR8 scenario, in order to consider more technological advancements to obtain a competitive SMF solution, in the short-distance application scenario, the cost is the focus of attention. The 800G optical module can use 800G SR8. In the evolution to 800G-SR8, single-channel 100G rates may limit solutions based on multimode fiber (MMF). 800G rate optical modules and coherent long-distance optical modules are the core unit modules to realize optical interconnection within and between data centers, and are the necessary foundation for building high-quality computing power networks. Therefore, the introduction of high-speed optical modules will continue to promote the construction of cloud computing data centers to meet its large data exchange needs.
