AI Data Center Optics are the optical components moving data between racks, switches and GPU clusters as AI workloads push interconnect speeds toward 800G and 1.6T. Copper cabling hits its physical limits at that scale. Silicon photodiodes cannot detect the infrared wavelengths these optical systems use. InGaAs and germanium photodiodes convert those wavelengths into usable electrical signals with the speed, low dark current, and reliability data centers require. GPD Optoelectronics designs and manufactures high-speed InGaAs photodiodes built for optical transceivers and data center infrastructure. In-house fabrication supports the volume, consistency and long-term availability that large-scale deployments need.
Everyone’s talking GPUs, but the AI buildout has a quieter bottleneck: getting data into and out of chips fast enough. As data centers push toward 800G and 1.6T, silicon can’t detect the light. Germanium and InGaAs photodiodes are the unsung heroes making it work.
