5500颗光引擎如何撑起4096卡超节点？华为NPO的故事还没讲完
Quick Answer
Huawei's Hi-ONE optical engine, capable of 7.2T bandwidth, will replace 48,000 800G pluggable modules with 5,500 units in the 4096-card Ascend 960 supernode, marking a significant advancement in AI computing architecture.
Quick Take
This NPO (Near-Packaged Optics) technology aims to enhance signal integrity and reduce latency by minimizing electrical connection lengths.
Key Points
- Hi-ONE integrates 36 optical transceiver channels, each with 200G capacity.
- NPO technology reduces the physical space required for optical interconnects to about 5 cm.
- The deployment of Hi-ONE will support a total bandwidth of approximately 39.6 Pb/s.
- Huawei collaborates with industry leaders to establish OPEN NPO standards.
- The design allows for redundancy, potentially leading to a 6.4T effective bandwidth in practice.
