Why ACCs Are Built for AI Scale-up and In-rack Connectivity
Marvell demonstrated its 200G/lane active copper cable technology for AI scale‑up and in‑rack connectivity at DesignCon 2026. In this video, Nicola Bramante showcases 200G/lane active copper cable technology in AI scale up and in rack connectivity. ACC is a technology that is an emerging alternative to pure copper cables; it allows for lower power, lower latency and lost cost. Marvell ACC solutions deliver longer reach, thinner cables and lower power compared to traditional copper, enabled by advanced analog equalization that exceeds competitive approaches. The demo features a 1.6T, two‑meter cable connected to a SerDes system emulating in‑rack traffic, with measured bit error rates between e‑8 and e‑9 across all lanes. Marvell ACC is a welcome addition to the AI scale up portfolio, which already includes PCIe, AEC, and AOC.
