证券研究报告 2025年08月11日 行业：通信 智算网络架构研究——光铜携手共进 通信行业专题研究 评级：强于大市（维持） 马成龙（分析师） S1160524120005 刘正（联系人） 投资摘要 AI集群网络架构升级，后端组网拉动光模块需求。传统的云数据中心网络流量主要是从数据中心到最终客户，以南北向流量为 主；AI集群东西向的通信流量占据主要部分，因此需增设后端网络实现各服务器间的互联，大幅拉动了光模块、交换机、网 卡、光纤光缆的需求。当前主流的AI后端网络以IB和以太网方案为主，尽管IB性能更加突出，但综合考虑成本和生态，我们认为 后续以太网方案将逐步占据主导地位。 英伟达GB300出货在即，1.6T光模块需求有望爆发。英伟达GB300有望于下半年出货，相比于GB200 NVL72 ，在交换设备层 面GB300 NVL72在网卡端和交换机端都做了升级。GB200采用CX7网卡，使用 Q3200 Quantum-3 交换机托盘，其包含 2 个独 立交换机，每个交换机有36个400Gb/s端口；GB300 采用CX8网卡，需配置Quantum-X800 QM3400交换机，其配有144个端 口，每个端口均 ...
