对于类似 NVLink 的私有标准而言,其更容易发挥其领域定制的优势,可以大胆采用例如定制连接器、线缆和模块, NPO (Near Package Optics),甚至 CPO (Co-Packaged Optics) 技术,以突破这一互联密度瓶颈。然而,对于以开放互通为目标,以实现广泛的兼容性和互通性为刚性要求的 Ethernet 而言,采用 NPO 和 CPO 使设备丧失...
采用硅光子的CPO技术是指把硅光模块和CMOS芯片用高级封装的形式(例如2.5D或者3D封装)集成在一起,从而在成本、功耗和尺寸上都进一步提升数据中心应用中的光互连技术。 CPO(Co-PackagedOptics,共同封装光学)是将交换芯片和光引擎共同装配在同一个Socketed(插槽)上,形成芯片和模组的共封装。CPO作为新技术趋势,尚未发展...
据不愿透露姓名的业内消息人士称,英伟达(NVIDIA)和台积电(TSMC)正在就硅光子学和名为共封装光学(CPO,co-packaged optics)的光组件封装展开合作,旨在通过实现更高的速度并提高能效来助力人工智能发展,这些消息人士认为这两家巨头在该领域处于领先的开发地位。
