在这个 MEMS 的光交换核心之外,还有配置 272 个 LC/APC 连接器的前面板、12 块高压驱动板、CPU 控制板、电源及风扇等,共同组成了一个完整的具备136×136 双工端口的 OCS。据论文《Mission Apollo: Landing Optical Circuit Switching at Datacenter Scale》数据,已有数万个 OCS 已经制造并被部署。--- 报告摘...
Google has replaced its spine switches with self-developed all-optical switches. Unlike the typical circuit packet switching form, the optical circuit switch (OCS) employs direct all-optical switching. Compared to Broadcom's or Mellanox's switch solutions, this significantly reduces the power consumpti...

The company is also working to connect South Africa to Portugal with a new submarine cable that Google says is the first subsea cable to “incorporate optical switching at the fiber-pair level rather than traditional wavelength-level switching.” Google is contracting Alcatel Submarine Networks to ...
Google 在论文《 Lightwave Fabrics:At-Scale Optical Circuit Switching for Datacenter and Machine Learning Systems》中认为,相较于数据中心网络连接,用于机器学习系统网络的光模块在高带宽、低延迟和同步特性有更高的要求, 与传统光模块有较大的差异,因此 Google 对光模块中的关键组件,如激光器,环行器,跨阻...
