In this episode, we look at the specific engineering shift from copper interconnects to silicon photonics inside hyperscale data centers. Lucas and Luna break down why Intel’s I-Macros and TeraPHY modulators are becoming essential for AI cluster scaling, specifically addressing the bandwidth-density wall that traditional electrical signaling hits around forty gigabits per second. We examine the thermal efficiency gains of moving light onto a silicon chip, the role of co-packaged optics in reducing latency, and why this hardware change matters for the future of machine learning infrastructure. This is a deep dive into the physical layer of the cloud, focusing on one concrete technology enabling the next generation of compute. #SiliconPhotonics #DataCenterHardware #IntelIbex #OpticalInterconnects #AIClusters #CoPackagedOptics #FexingoBusiness #BusinessPodcast #TechInfrastructure #BandwidthScaling #ElectricalToOptical #ModulatorDesign #LatencyReduction #HyperscaleComputing #NetworkEngineering #ChipletArchitecture #EnergyEfficiency #FutureOfCompute Keep every episode free: buymeacoffee.com/fexingo
