Huawei Optical Chips and Modules

Huawei develops both high-performance optical modules and in-house optical chips, integrating them to enable ultra-high-speed, reliable, and scalable optical networks.

Optical Modules

Huawei offers a full range of optical modules from GE to 800GE, designed for data centers, enterprise networks, and carrier infrastructure. These modules emphasize three core capabilities: Spanning (ultra-long transmission), Stable (high reliability), and Secure (robust security), ensuring resilient interconnectivity in AI-driven networks. Huawei's modules are pluggable and flexible, supporting multiple interface types and high-density, low-power designs with 25G, 50G, or 100G per lane configurations.

Proprietary solutions include co-packaged optics (CPO) and silicon photonics-based modules, which integrate closely with switches and routers to reduce power consumption and insertion loss.

Optical Chips

Huawei invests heavily in optical chip development, producing core components such as lasers, modulators, and photodetectors in-house. Key technologies include:oDSP (Optical Digital Signal Processing) chips in the OptiXtreme series, supporting adjustable single-wavelength rates from 100G to 600G, with spectrum efficiency up to 8 bit/s/Hz, and single-fiber capacities reaching 96Tbps. Thin Film Lithium Niobate (TFLN) modulators, which increase bandwidth by 50% and reduce power consumption by 30% compared to traditional indium phosphide modulators, enabling single-wavelength terabit transmission.

Indium Phosphide (InP) chips, developed through strategic investments in companies like Milphoton Semiconductor, supporting 800G and 1. 6T high-speed optical modules, 6G all-photonic wireless base stations, and AI data center interconnects.

Integration and Strategic Focus

By controlling both chip and module design, Huawei achieves vertical integration, improving performance, reliability, and supply chain security. Optical chips and modules are deployed across data centers, metropolitan networks, long-haul transmission systems, and 5G backbones, enabling high-speed, low-latency, and scalable connectivity. Huawei also integrates AI algorithms and system-level innovations to enhance network autonomy and optimize optical interconnect architectures.

Future Directions

Huawei continues to advance photonic integration, AI-driven optical networks, and quantum technologies, aiming to reshape intelligent computing infrastructure. Investments in InP-based chips and co-packaged optics indicate a focus on next-generation 6G networks, terabit-level transmission, and high-speed AI data center interconnects. These developments position Huawei as a leading player in both optical module manufacturing and optical chip innovation.
