Huawei unveils Hi-ONE NPO optical engine deployment: 5,500 units for 4,096-card Ascend 960 supernode
Huawei has announced a deployment plan for its HiSilicon-developed Hi-ONE optical engine, using near-package optics (NPO) in a 4,096-card Ascend 960 supernode. The design replaces 48,000 800G pluggable optical modules with 5,500 Hi-ONE units, each carrying 7.2T of bandwidth across 36 200G lanes. A cross-cabinet interconnect device supports 176 1.6T ports and about 280T of all-optical interconnect bandwidth. Huawei says this would be the first AI supernode to use NPO.
Huawei also launched an OPEN NPO standards initiative with Baidu, JD Cloud, China Mobile Research Institute and optical component makers.
