Optical PCIe technology promises extended reach for AI data center designs

By PulseAugur Editorial · [1 sources] ·

Companies like Lumentum, Astera Labs, and Corning are demonstrating optical PCIe technology as a potential solution to the limitations of traditional copper interconnects in AI data centers. This technology transmits data as light over fiber optic cables, extending reach beyond the few meters typically supported by copper. The demonstration at the OCP Global Summit showcased how optical PCIe could enable more flexible and disaggregated AI rack designs, allowing for better optimization of compute density, power, and cooling.
