High-speed cables (DAC, Direct Attach Cable) include passive copper cables, active copper cables (ACC), and active cables (AEC). They are significantly cheaper than fiber optics, which can greatly reduce the costs of data centers. Compared to DAC, active optical cables (AOC) offer advantages such as being lighter, smaller, having lower error rates, and supporting longer … Read more
Previously, we wrote an article about the NVL72 interconnection scheme, and some users in the community asked for an introduction to the meanings of these different cables in data centers. Let’s review where optical and copper interconnections are used in GB200. The Abandoned NVL72 Optical Interconnection Scheme There has been much discussion about the architecture … Read more
