对于连接1,024个NPU的SuperPoD的跨机架互联，32个LRS中每个都有4x100G连接到6个相邻机架的6个对应LRS。跨机架连接使用华为自研的StarMatrix 800G LPO可插拔光模块。由于是LPO，不需要光DSP，这显著降低了光模块成本和功耗。在路线图上，华为尚未决定下一代Ascend 960系统是采用NPO还是继续使用1.6T LPO可插拔光模块。(3/4)

For inter-rack connectivity to the 1,024 NPUs SuperPoD, each of the 32 LRS has 4x100G going to 6 other corresponding LRS to 6 neighboring racks. The inter-rack connection uses Hauwei’s own StarMatrix pluggables 800G LPO pluggable transceivers. As they are LPO, optical DSPs are not required, which significantly reduces transceiver cost and power. On the roadmap, Huawei is still undecided whether to implement NPO or stick with 1.6T LPO pluggables for the next gen Ascend 960 system. (3/4)
