Data centers are filling up with optical transceivers. Every jump to 400G, 800G and now 1.6T means more links, more density and more power. At first, optics looks like a way to reduce copper. In some ways, it does. Inside racks, copper is being replaced for high-speed data links as signal loss and heat become limiting factors. But zoom out and the picture flips. The total amount of copper per data center is actually increasing, not decreasing. A traditional data center might use around 5,000-15,000 tons of copper, while modern AI-driven hyperscale sites can reach up to ~50,000 tons. We’re using less copper per bit of data, but far more copper per data center. Looking ahead, this trend will continue. Data centers already consume around ~500,000 tons of copper per year globally, and projections suggest this could grow to ~3 million tons annually by 2050: a ~6× increase. The driver is simple: power. AI clusters are pushing rack densities higher, which means more copper in cables, busbars, transformers and cooling systems. The industry will try to slow this growth through better efficiency, higher voltage distribution and deeper optical integration. Copper isn’t going anywhere: it’s becoming even more critical.
