Huawei Networking News: New SF9300 and XH9300-EN Switches Lead HUAWEI CONNECT 2026

By: Network-Switch.com | September 21, 2026

Quick Summary

Huawei's September 13-20 networking news was dominated by HUAWEI CONNECT 2026 in Shanghai. Unlike several recent weeks focused mainly on market data and regional events, this period brought new enterprise network hardware. Huawei introduced the UBG SF9300 switch series and CloudEngine XH9300-EN NPO switches for AI data center fabrics, upgraded its Stellar AI WAN and AI Campus architectures, and released a new carrier B2B ICT solution combining routing, Wi-Fi 7, FTTO and unified management. Reuters and the Associated Press also covered HUAWEI CONNECT 2026, although their reporting focused primarily on Huawei's wider AI computing roadmap rather than the enterprise-network products covered here.

HUAWEI CONNECT 2026 Puts AI Infrastructure at the Center of Enterprise Networking

HUAWEI CONNECT 2026 ran in Shanghai from September 17 to 19, with more than 300 keynotes, summits and sessions and a 22,000-square-meter exhibition area. Huawei used the event to present new AI infrastructure, enterprise networking, storage, cloud and industry solutions.

For enterprise networking, the central theme was that AI workloads are changing the role of the network. Higher east-west traffic, distributed computing and always-on agent workloads require lower latency, stronger resilience and more autonomous operations across data center, WAN and campus environments.

Reuters and the Associated Press independently covered the conference, concentrating primarily on Huawei's AI chips, SuperPoD systems and broader challenge to Nvidia. Those reports confirm the scale and strategic importance of the event, while the detailed networking specifications below come from Huawei's product announcements.

Huawei Introduces SF9300 and XH9300-EN Switches for AI Networks

The strongest product news of the week was Huawei's upgraded Stellar AI Fabric architecture. Huawei introduced the UBG SF9300 series, designed to work with Ascend A5 and A6 computing platforms in AI clusters. Huawei says a two-layer multi-plane architecture can eliminate a traditional core layer, while its unified protocol reduces end-to-end latency from 20 microseconds to 11 microseconds.

Huawei also introduced the CloudEngine XH9300-EN series of 51.2T near-packaged-optics switches. According to Huawei, the centralized light-source architecture reduces interconnect power consumption from 1,000 W to 600 W, while the near-packaged design cuts optical-electrical conversion latency by 180 ns. A snap-fit optical structure is intended to make field replacement faster.

These figures are Huawei-reported performance claims and should not be treated as independent benchmark results.

Network-Switch.com observation: The more important design trend is the move toward tighter compute-network integration. For AI clusters, switch selection is increasingly driven by fabric scale, link-flap behavior, optical power consumption and recovery time rather than only port count and nominal interface speed.

Stellar AI WAN Targets Long-Distance AI Computing and Secure Transport

Huawei also upgraded its Stellar AI WAN Solution on September 17. The architecture targets enterprises that need to access compute resources across regions without moving all raw data or deploying full local AI infrastructure at every branch.

Huawei's new XH computing-network appliance uses model partitioning to keep initial and final inference layers on-premises while transmitting intermediate vectors across the network. Huawei says its updated Starnet lossless algorithm can support remote computing over distances of 1,000 km while improving computing efficiency and reducing bandwidth requirements.

The WAN architecture also includes device-, link- and network-level security. Huawei continues to use technologies such as intrinsic security, APN6 traffic fencing and quantum-secure links in this architecture, although several of those security concepts were introduced in earlier regional announcements.

Network-Switch.com observation: The new element worth watching is the compute-network appliance and model-partitioning approach. Enterprises evaluating remote AI inference should still measure real application latency, packet loss, bandwidth cost, privacy requirements and failure behavior before assuming remote compute can replace local infrastructure.

Stellar AI Campus Adds Wi-Fi 7 Advanced, eCampusLink and HiSpaceX

Huawei's upgraded Stellar AI Campus Network adds new capabilities across wireless performance, security and autonomous operations. Huawei introduced intelligent Coordinated Scheduling and Spatial Reuse, or iCSSR, for Wi-Fi 7 Advanced and says the technology can improve wireless performance in coordinated multi-AP environments.

Huawei also debuted the eCampusLink platform and HiSpaceX appliance for unified access, spatial modeling and orchestration across digital campus environments. The upgraded Asset Security Solution is designed to identify and block abnormal endpoint behavior more quickly, while iFlow and distributed real-time simulation are used for proactive detection, fault localization and post-change verification.

Huawei reports 95% troubleshooting accuracy and a 90% reduction in mean time to repair for the upgraded operations framework. These are vendor-reported figures rather than independent testing.

Network-Switch.com observation: Wi-Fi 7 capacity alone does not determine campus performance. AP placement, 2.5GE or 5GE access, PoE headroom, 10GE aggregation, roaming design and RF conditions still determine whether advanced scheduling produces measurable gains in a real network.

Huawei Releases a Converged B2B ICT Networking Solution for Carriers

Huawei also introduced a new high-quality ICT solution for carrier B2B services during HUAWEI CONNECT 2026. The networking portion combines a six-in-one high-performance router for low-latency multi-uplink WAN connectivity with Wi-Fi 7 access points that integrate IoT and channel-state-information sensing.

The solution also combines FTTO with video infrastructure and uses HiSec Endpoint, iMaster NCE-HisecInsight and the broader iMaster NCE platform to manage LAN, WAN, security, storage and collaboration services through a more unified operational model.

Network-Switch.com observation: This is primarily a service-provider architecture rather than a single enterprise SKU. Its significance is the packaging model: routing, WLAN, optical access, video and security are increasingly sold as one managed ICT service. Enterprise customers should still separate the architecture into individual BOM, licensing and lifecycle components before procurement.

This was the most product-focused Huawei networking week since the August eKit announcements. The SF9300 and XH9300-EN are genuinely new switch families rather than another regional re-release of an existing solution. The WAN and campus updates also add new components such as the XH computing-network appliance, eCampusLink and HiSpaceX.

For buyers, however, HUAWEI CONNECT announcements are the start of technical evaluation rather than the end. Before these products enter a production BOM, verify final datasheets, supported optics, interface combinations, software releases, licensing, power requirements, regional availability and interoperability with the existing network.

Reuters and AP independently covered HUAWEI CONNECT 2026 but focused mainly on Huawei's AI computing roadmap. No directly relevant CNN or BBC report on the new SF9300, XH9300-EN, AI WAN or AI Campus announcements was identified in the September 13-20 window. Previously covered AIFW white-paper material and older regional versions of Stellar AI Fabric, WAN and Campus were not treated as new unless the September HUAWEI CONNECT release added a genuinely new product or capability.
