Broadcom Announces Tomahawk 6 – Davisson, the Industry’s First 102.4-Tbps Ethernet Switch with Co-Packaged Optics

Breakthrough 102.4-Tbps CPO Ethernet Switch Delivers Unmatched Power Efficiency and Link Stability to Enable Cluster Scale-Up and Scale-Out

PALO ALTO, Calif., Oct. 08, 2025 (GLOBE NEWSWIRE) -- Broadcom Inc. (NASDAQ: AVGO) today announced that it is now shipping Tomahawk 6 – Davisson (TH6-Davisson), the company’s third-generation Co-Packaged Optics (CPO) Ethernet switch. Designed specifically for the accelerating demands of AI networking, TH6-Davisson is the industry’s first to deliver an unprecedented 102.4 terabits per second of optically enabled switching capacity. Doubling the bandwidth of any CPO switch available today, TH6-Davisson sets a new benchmark for data center performance. Built on Broadcom’s foundation of CPO innovation and field shipments, the platform doubles the bandwidth of any CPO switch available today, while delivering major advancements in power efficiency and traffic stability to unlock optical interconnect performance required to scale-up and scale-out the world’s most demanding AI clusters.

“TH6-Davisson, our third-generation CPO Ethernet switch, represents a significant advancement for AI infrastructure,” said Near Margalit, Vice President and General Manager, Optical Systems Division, Broadcom. “By enhancing link stability and energy efficiency, we’re enabling smoother, more cost-effective AI model training. We designed this platform to scale large AI clusters by delivering on the three imperatives for optical interconnect: higher model FLOPs utilization, reduced job interruptions, and improved cluster reliability.”

CPO: Purpose-Built for AI Networking

The rise of large-scale AI training and inference is driving unprecedented east-west traffic in data centers, as XPUs and GPUs exchange vast datasets across tens of thousands of servers. Traditional pluggable optics are straining under this growth—consuming more power, introducing higher latency, and demanding larger system footprints. TH6-Davisson embodies Broadcom’s lead-edge and robust CPO architecture that has been fine-tuned over multiple generations of development to overcome these barriers and deliver the bandwidth, efficiency, and reliability required for next-generation AI networks.
