1、英伟达最近发布的方案中，涉及到的光模块和交换机配置，NVL576方案采用了光引擎而非传统光模块进行互联。具体而言，一个柜子里需要插入648个3.2T的光引擎，每个早期3.2T光引擎大概在2000美元左右。（目前这个方案还没有定）
2、NVIDA Rubin：全液冷散热架构解读及对数据中心的影响
大概率采用了微通道冷板技术。冷板供应商，去看尚无明显改变。全球范围内，与英伟达合作紧密的ABC和Coo1IT等公司已经提供微通道技术支持，并在2025年10月至12月间完成送样测试且通过验证。在国内市场，目前英维克与思泉正在向英伟达提供微通道技术相关样品，但截至2026年1月尚无测试结果反馈。
3、光模块的制冷器TEC的主要生产商大和热磁的2026年出货量显著增长，2026年有望翻倍。大和热磁占据全球tec市场约60%的份额。
