AI Chips Are Getting Faster. Why Are Data Centers Spending Billions Replacing Copper Cables?

AI data centers are investing in optical technology to replace copper cables, as faster processors create bottlenecks. Coherent, an optical tech manufacturer, reported a 50% YoY revenue increase, with its Data Center & Communications segment growing 79% YoY to $1.95B. The shift is driven by the need for faster data transfer in large AI clusters, though copper remains cost-effective for short distances.
