OCS为何成为光博会焦点?9月28日,和讯投顾邓雄表示,光信号直接通过光路交换,无需电信号转换,延迟接近0(谷歌测试显示比电交换快1000倍)。省去光电转换环节,数据中心整体能耗大幅下降,AI训练效率提升30%。单根光纤理论带宽达100Tbps(可同时传输5万部4K电影),满足万卡级GPU集群互联需求。
行业方面,H100服务器需求单卡需800Gbps带宽,传统电交换无法支撑万卡级集群高效互联。能耗痛点,光电转换占数据中心总用电40%,OCS省去该环节,年省电费上亿元。灵活扩展方面,支持热插拔,扩容如“搭积木”,适配AI算力快速迭代需求。
OCS市场前景广大。2026年千亿规模,年复合增长率67%。AI巨头已向中国厂商下订单,验证技术成熟度。国家算力枢纽建设、东数西算工程加速OCS渗透。中国厂商在核心部件(如钒酸异晶体、激光微透镜)实现国产替代,毛利率超60%。
投资逻辑方面,关注三大核心赛道。整机赛道,技术门槛最高,整机集成能力是核心竞争力,绑定头部客户者胜出。核心部件赛道,国产替代重点,部件性能直接影响OCS效率,高壁垒、高毛利。光纤配套赛道,光纤质量决定传输损耗,头部厂商占据先发优势。
