Huawei MWC optical module

Huawei unveiled advanced StarryLink and single-wavelength 2T optical modules at MWC 2025 and 2026, enhancing data center and high-capacity network performance.StarryLink Optical Modules (MWC 2025)

At MWC 2025, Huawei introduced the StarryLink optical modules, designed to improve network performance with "3S" quality: Spanning, Stable, and Secure . These modules address key challenges in modern data centers:

• Transmission Distance: Optimized optical path coupling doubles the transmission distance compared to industry averages.
• Reliability: Enhanced design reduces failures and contamination risks.
• Security: Protects sensitive data during cross-equipment interconnections. StarryLink modules support high-speed interconnections, evolving from 56 Gbit/s to 112 Gbit/s per lane, meeting the growing demands of AI-driven data center traffic .

Single-Wavelength 2T Optical Solution (MWC 2026)

At MWC 2026, Huawei unveiled the world's first single-wavelength 2 terabit-per-second (2T) optical solution . Key features include:

• Multi-Rate Flexibility: Supports 800G, 1.2T, 1.6T, and 2T on the same hardware, allowing adaptation to different network reach and capacity requirements.
• Extended Transmission Distance: Achieves 30% longer reach than industry averages, reducing the need for regeneration points and amplifier sites.
• Submarine Cable Support: Capable of rates beyond 1T per wavelength over tens of thousands of kilometers, lowering per-bit costs for global backbone networks. This solution is particularly suited for data center interconnects (DCI) and metro-area high-density networks, addressing the surge in AI-generated traffic.

AI Data Center Optical Modules

Huawei also launched high-speed StarryLink optical modules for AI data centers, integrated into the Xinghe AI Fabric 2.0 Solution . Highlights include:

• 800GE and 400GE modules with twice the reliability and extended range.
• Integration with 51.2T liquid-cooled switches, enhancing AI-driven data center performance.
• Support for automation, efficiency, and resilience in large-scale AI workloads.

Enterprise and Industry Applications

Beyond data centers, Huawei's optical solutions support:

• iFTTO and next-gen FAN networks for campus and home networks.
• Fiber sensing solutions for transportation and manufacturing sectors.
• AI-enabled network intelligence for ISPs and enterprise digital transformation .

Summary

Huawei's MWC optical module innovations demonstrate a clear focus on high-speed, reliable, and secure optical networking. From StarryLink modules for data centers to the groundbreaking single-wavelength 2T solution, these technologies address the growing demands of AI traffic, long-distance transmission, and enterprise digital transformation, positioning Huawei at the forefront of optical transport evolution.
