Evidence
Nvidia is looking into using co-packaged Copper to reduce loss further, in case NPC doesn’t work
Context After
Rubin Ultra NVL288
Though not officially discussed by Nvidia at GTC 2026, an NVL288 concept has been explored within the supply chain. This would entail two NVL144 Kyber racks placed adjacent to each other, with a rack-to-rack copper backplane used to connect the two racks. One possibility is that all 288 GPUs are connected all to all, but this would require higher radix switches than the current NVLink 7 switches which only offer a maximum radix of 144 ports of 200G.
② Atomic Claim
若 NPC 方案不可行，Nvidia 正研究採用 co-packaged Copper 以進一步降低訊號損耗。
