Key partner milestones with CPO switches demonstrate ecosystem readiness for next-generation AI scale-up and scale-out networks
Broadcom’s Legacy in CPO
Broadcom’s leadership in CPO began in 2021 with its first-generation Tomahawk 4-
Building on that success, the second-generation Tomahawk 5-Bailly (TH5-Bailly) chipset became the industry’s first volume-production CPO solution. As part of the TH5-Bailly production, Broadcom focused on automated testing and scalable manufacturing processes, setting the stage for high-volume production of future generations. The deployment of Broadcom’s 100G/lane CPO product line has enabled the company to gain unmatched expertise in CPO system design, seamlessly integrating optical and electrical components to maximize the performance while delivering the lowest power optical interconnects in the industry.
Today, with the announcement of the third-generation 200G/lane CPO product line, alongside commitment to developing a fourth-generation 400G/lane solution, Broadcom continues to lead the industry in delivering the lowest power and highest bandwidth density optical interconnects.
A Rapidly Developing CPO Ecosystem
Broadcom’s leadership in CPO is driven not only by its cutting-edge switch ASICs and optical engine technology but also by a comprehensive ecosystem of passive optical components, interconnects, and system solutions partners. Through its 100G/lane CPO product line, Broadcom has proven its ability to scale its technology, meeting the growing demands of inference-based AI and supporting the next wave of AI-driven applications.
“Broadcom has spent years perfecting our CPO platform solutions, as evidenced by the maturity of our second generation 100G/lane products and the ecosystem readiness,” said Near Margalit, Ph. D., vice president and general manager of the Optical Systems Division, Broadcom. “With our third-generation 200G/lane CPO solutions, we are once again setting the bar for the next-generation of AI interconnects. Our commitment to delivering the industry-leading performance, power efficiency, and scalability will help our customers meet the demands of today’s rapidly evolving AI infrastructure.”
Key Partner Milestones Towards Mass Deployment
Broadcom’s advancements in CPO technology are supported by the growing number of key publicly announced partnerships across the ecosystem, as several major collaborators announced significant milestones this week:
- Corning Incorporated announced collaboration with Broadcom on advanced fiber and connector technology including shipments of components on the TH5-Bailly platform.
- Delta Electronics announced production for the TH5-Bailly 51.2T CPO Ethernet switch in a compact 3RU form factor, available in both air-cooled and liquid-cooled configurations.
Foxconn Interconnect Technology revealed the production release of CPO LGA sockets and Pluggable Laser Source (PLS) cages and connectors, critical components for ensuring reliable, high-performance system integration.- Micas Networks announced production of the TH5-Bailly network switch system that delivers more than 30% system level power savings compared to systems with traditional pluggable modules.
- Twinstar Technologies celebrated milestone volume shipments of high-density CPO fiber cables, further enabling the scaling of optical interconnects in next-gen data center infrastructures.
These partner milestones demonstrate the continued progress in building a complete, fully integrated CPO ecosystem that enables the next generation of AI networking solutions.
Gen 3 CPO: Unlocking 200G/lane CPO Systems
Broadcom’s 200G/lane CPO technology is designed for next-generation, high-radix scale-up and scale-out networks, which will demand parity with copper interconnect reliability and power efficiency. This capability is crucial for enabling scale-up domains exceeding 512 nodes, while also addressing the bandwidth, power, and latency challenges associated with the increasing size of next-generation foundation model parameters.
Broadcom’s Gen 3 solutions are engineered to address scale-up interconnects, where issues such as link flaps and operational disruptions can significantly affect the industry’s ability to achieve the lowest cost per token. Broadcom’s Gen 3 and 4 roadmap includes close collaboration with ecosystem partners to optimize the integration of CPO solutions, ensuring they meet the demanding requirements of hyperscale data centers and AI workloads. Additionally, Broadcom remains committed to open standards and system-level optimization, which are essential to the continued success and evolution of our CPO technology.
