Optical interconnects are becoming a critical bottleneck in AI data centers, overshadowing the role of GPUs. As AI operations scale, the ability to transfer data between GPUs efficiently is crucial, with optical interconnects providing the necessary bandwidth. The shift from copper cables to fiber optics is driven by the need for higher transmission speeds and reduced power consumption, as copper cables reach their physical limits. The optical interconnect industry is poised for significant growth, with the market expected to exceed $110 billion by 2030. Co-Packaged Optics (CPO) is emerging as a transformative technology, integrating optical components directly with GPUs to enhance data transfer efficiency. This shift is creating new opportunities across the supply chain, from silicon photonics foundries to external laser suppliers, as companies like NVIDIA and Broadcom adopt CPO solutions to meet the demands of next-generation AI platforms.
