Great find Pro!
Broadcom has introduced the Tomahawk6 Davisson CPO Switch earlier at OFC25, which is based on 200G/L, but they are working (ie OFC 2026 introduction?) on the 400G/L successor...
Video Key Takeaways Include:

🔹Groundbreaking bandwidth and efficiency: The TH6-Davisson delivers 102.4 Tbps bandwidth, doubling the capacity of any current CPO switch, while significantly reducing power consumption and improving network stability.

🔹Industry-first integration and performance: The platform directly integrates optical engines with the switch package, offering a 70% reduction in optical interconnect power usage and higher model FLOPs utilization for demanding AI and cloud clusters.

🔹Broadcom’s evolving CPO approach: Designed for seamless interoperability, TH6-Davisson connects with DR-based and NPO/CPO optical interconnects at 200 Gbps per channel, supporting frictionless connectivity for advanced NICs, XPUs, and fabric switches.

🔹Generational advancement and future roadmap: Building on a foundation of innovation across three generations, Broadcom is progressing to a fourth-generation solution targeting 400 Gbps per-channel bandwidth, enhanced efficiency, and sustainability for hyperscale data centers.

Great video, Thanks!
