Enhanced Key Takeaways
- •The 7.2 Tbps module was unveiled at the China International Optoelectronic Exposition (CIOE) in Shenzhen, powered by Huawei's Hi-ONE silicon photonics platform.
- •The architecture aggregates 36 channels running at 200 Gbps each, utilizing wavelength-division multiplexing (WDM) to route 36 Tx and 36 Rx channels across 18 Tx and 18 Rx signal fibers.
- •Built on a silicon nitride-on-silicon-on-insulator (SiN-SOI) platform, the NPO module slashes power usage by 60% to 65%, footprint by 90%, and total laser component count by 88% compared to traditional pluggable optics.
- •Huawei specifically engineered the module to integrate directly into its Ascend-based compute clusters and SuperPoD AI supercomputing scale-up fabrics.
- •To drive broader adoption, Huawei co-led the NPO Standards Industry Summit with IPEC in Shenzhen on September 10, 2026, alongside over 40 ecosystem participants while championing NPO specifications within the OIF.

Technical Deep Dive
- Channel Configuration: 36 independent transmit (Tx) and 36 receive (Rx) channels operating at 200 Gbps per lane, delivering 7.2 Tbps unidirectional aggregate throughput.
- Silicon Photonics Substrate: Fabricated using a hybrid silicon nitride-on-silicon-on-insulator (SiN-SOI) optical platform.
- Multiplexing & Optical Interface: Leverages wavelength-division multiplexing (WDM) to combine channels into 18 Tx and 18 Rx physical optical fibers.
- NPO Design Advantages: Positions optical engines adjacent to switching ASICs to shorten high-frequency electrical traces while retaining modular detachability, field serviceability, and standard supply chain compatibility over CPO.
- Efficiency Benchmarks: Achieves a 60% to 65% power reduction, 90% footprint reduction, and an 88% reduction in required discrete laser components compared to equivalent-bandwidth front-panel pluggable optics.
Future ImplicationsAI analysis grounded in cited sources
Huawei will solidify proprietary scale-up advantages for Ascend SuperPoDs
Deploying 7.2 Tbps NPO directly mitigates inter-processor communication bottlenecks in Ascend clusters independently of Western optical interconnect supply chains.
NPO will gain market preference over CPO in near-term AI cluster deployments
The lower manufacturing risk and field-serviceable nature of NPO provide hyperscalers with a viable balance between high-bandwidth efficiency and modular repairability.
