行业投资要点

AI驱动算力需求激增，光通信迎来新增长空间。OpenAI发布的ChatGPT引发全球AI军备竞赛，2023年起海外客户对800G、400G光模块需求爆发，国产厂商如中际旭创、新易盛等占据全球市场份额前列，技术演进方向包括LPO低功耗方案、CPO封装集成、硅光子技术等。预计至2029年全球光模块市场规模年复合增长率达11%。

英伟达Blackwell平台推动算力结构升级：新一代AI芯片GB200配合液冷技术，进一步提升能效和传输效率，带动16T光模块需求。IDC领域方面，超大型数据中心数量快速增加，中国服务器市场向国产化迁移带来国产算力机会，例如中国电信AI服务器集采规模超84亿元。

技术趋势上，铜缆与光模块协同构成高速网络方案；高端PCB需求随服务器和交换机升级增长，沪电股份、中际旭创成为受益标的。风险包括AI技术应用不及预期、中美摩擦加剧政策风险等。

重点标的

中际旭创：国内光模块龙头，800G模块市占率第一，研发持续推进LPO、CPO技术。
新易盛、天孚通信：光模块细分领先企业，国产化进程加速。
中兴通讯、中国移动：运营商地位稳固，AI服务器集采推动国产替代。

风险提示

AI技术进展或市场需求放缓；
国际资本开支低于预期；
算力设备价格竞争导致盈利能力下滑。

English Summary

Key Investment Points

AI-driven demand surge fuels optical communication growth. OpenAI’s ChatGPT sparks global AI competition, leading to explosive market for 400G and 800G optical modules starting in 2023. China-based manufacturers like ZX Interwave lead globally, with emerging technologies such as LPO energy-saving modules, CPO co-packaged optics, and silicon photonics. The global optical module market is forecasted to grow at an 11% CAGR by 2029.

NVIDIA’s Blackwell architecture powers the next wave of AI computing with GB200 chips and liquid cooling enhancements. Increased efficiency and bandwidth meet the demands of high-performance computing clusters. Domestically, China's server market is pivoting toward homegrown AI solutions, exemplified by China Telecom's procurement of RMB 8.4B in AI server projects.

Market trends point to synergy between copper cabling and optical modules for high-speed networking. Shanghai Hupinyi captures opportunities via high-density PCBs for AI servers and switches. Risks include delays in AI adoption, reduced international spending, or heightened competition pressuring profit margins.

Key Companies

ZX Interwave: Leading domestic optical module provider advancing LPO/CPO tech.
Innomar Communications, Infinite Potential: Emerging players growing in optical module share.
Zhongxing Communications, China Mobile: Telecom giants driving domestic server/infrastructure investment.
