OFC 2026: Ayar Labs and Wiwynn Partner to Bring Co-Packaged Optics to Rack-Scale AI Systems

Ayar Labs, a player in co-packaged optics (CPO) solutions for AI scale-up, and Wiwynn, an innovative cloud IT infrastructure provider for data centers, announced a strategic partnership to deliver optically connected, rack-scale AI systems that support next-gen hyperscale AI workloads.As AI models drive compute demand, traditional copper interconnects increasingly constrain performance, system growth, and power efficiency. By combining Ayar Labs’ CPO solution with Wiwynn’s rack-level system design and manufacturing capabilities, the two companies are enabling a new class of rack-scale AI infrastructure that’s not constrained by the bandwidth and reach limitations of copper.

“AI infrastructure is outgrowing the limits of copper, and hyperscalers need a fundamentally new approach to scale,” said Mark Wade, CEO and co-founder, Ayar Labs. “Optically connected racks eliminate the interconnect bottleneck and unlock the next order of magnitude in performance and efficiency. By combining Wiwynn’s global system and manufacturing leadership with Ayar Labs’ co-packaged optics expertise, we are delivering pioneering, rack-scale architectures purpose-built for optically connected scale-up AI networks.”

The joint solution integrates Ayar Labs’ AI scale-up CPO technology, including TeraPHY optical engines powered by the SuperNova remote light source, into Wiwynn’s rack-level architecture for next-gen data centers. Together, the companies are solving the practical deployment challenges hyperscalers face, including optical fiber management, integration of CPO-enabled AI ASICs, thermal management, power efficiency, and manufacturability.

“Silicon photonics is reshaping how AI infrastructure is built,” said William Lin, president and CEO, Wiwynn. “With Ayar Labs’ leadership in co‑packaged optics and Wiwynn’s strengths in rack‑level integration and manufacturing, we accelerate the shift from silicon‑ready innovation to system‑ready solutions. Together, we are enabling advanced optical I/O that delivers greater scalability and energy efficiency for cloud and hyperscale customers, powering next‑gen AI data centers.”

The new optically-connected rack-scale AI infrastructure is designed to scale to 1,024 AI accelerators and beyond, with each accelerator capable of delivering more than 100 Tbps of optical connectivity, enabling thousands of accelerators to operate as a single, unified system across multiple racks. The solution incorporates a liquid-cooled architecture optimized for high-power operation, including support for external laser small form factor pluggable (ELSFP) light sources, advanced fiber management, and serviceable system designs required for hyperscale environments.

Wiwynn brings over a decade of experience delivering rack-level IT solutions to the world’s leading cloud service providers, with end-to-end capabilities spanning board design, system integration, and high-volume L10 and L11 rack delivery. The company has shipped general and AI servers to more than 750 data centers worldwide, supported by manufacturing operations in Taiwan, the United States, Mexico, Malaysia, and the Czech Republic.
