• Huawei unveiled the Atlas 960E SuperPoD with up to 4,096 Ascend 960 NPUs and Hi-ONE near-packaged optical interconnects
  • Huawei says 5,500 Hi-ONE engines replace 48,000 800G optical modules and cut interconnect power by more than 550kW

The Fact

Huawei unveiled the Atlas 960E SuperPoD at Huawei Connect in Shanghai on 17 September, pairing its next Ascend 960 processors with Hi-ONE near-packaged optics. The company says a single system can connect up to 4,096 NPUs, provide 8 EFLOPS of FP8 compute and carry as much as 1PB of high-bandwidth memory.

Each Hi-ONE optical engine is rated at 7.2Tbps and places the optical interface closer to the system electronics than conventional faceplate transceivers. Huawei says 5,500 Hi-ONE units can replace 48,000 800G optical modules and reduce interconnect power by more than 550kW.

Those power and reliability figures are Huawei's comparisons rather than independent customer measurements. The Ascend 960DT is scheduled for the first quarter of 2027, with the 960PR planned for the third quarter.

The assessment

Huawei is changing where the optical network can be serviced inside a very large AI system. Conventional pluggable transceivers sit at the front of equipment and can usually be replaced as individual modules. Moving the optics closer to the system electronics can shorten high-speed electrical paths and reduce the number of separate modules, but buyers need to know what hardware must be taken out of service when an optical engine fails.

That makes repairability part of the power calculation. A lower module count is useful if the resulting system can be maintained without turning a small optical failure into a longer or wider outage. Huawei has published availability claims, but not field failure rates, replacement granularity or customer repair times for production Atlas 960E systems.

For BTW readers, Huawei's NPO design moves qualification beyond bandwidth and power. Buyers need production data showing how often Hi-ONE fails, what must be replaced and how quickly the SuperPoD returns to full capacity.

What to watch

Watch the first production shipments of Ascend 960DT and Hi-ONE, followed by customer data on optical failure rates, mean time to repair and complete-system power. Service documentation showing whether a failed engine can be replaced independently, and what capacity is interrupted during the procedure, will make the maintenance trade-off clearer.
