Thomas Barber, Vice President, Communications Infrastructure and Datacenter at GlobalFoundries, explains how the adoption of silicon photonics in data centres enables ultra-fast data transmission between GPUs at double the speed, enhancing the efficiency and performance of communication systems to meet today’s demand for generative AI, while also providing a more sustainable method of data processing. Thomas also discusses other power management solutions that can save up to 10% of data centrepower consumption, and the promise of RF GaN technology for future communication needs.
