华福证券：AI大模型训练进入“万卡集群”时代 OCS交换机有望步入发展快车道

Group 1 - The core viewpoint is that as AI large model training enters the "ten thousand card cluster" era, traditional electrical switching network architectures face high power consumption and bandwidth requirements, making OCS switches essential for ensuring extreme bandwidth and forward compatibility through their "all-optical switching" mechanism [1] - The global OCS switch market is projected to grow from $72.78 million in 2020 to $366.47 million by 2024, with a CAGR of 49.80% from 2020 to 2024, and expected to reach $2022.21 million by 2031, with a CAGR of 17.12% from 2025 to 2031 [2] - The MEMS technology solution currently dominates the commercial OCS switch market, accounting for over 70% of the market share, with Google being the largest producer [2] Group 2 - Domestic manufacturers are actively participating in the R&D and manufacturing of OCS switches, with companies like Huawei launching new all-optical switches and others like Lingyun Optics and Zhongji Xuchuang involved in the development and manufacturing processes [3] - A list of recommended stocks in the OCS industry chain includes companies such as Saiwei Electronics, Xindong Link, Juguang Technology, and others, indicating a robust investment opportunity in this sector [4]
