IBM has developed a silicon photonics technology that could speed data center training by as much as 5×. The company designed and assembled what it calls the first successful polymer optical waveguide (PWG) behind the technology. IBM said the tech will also cut costs for scaling generative AI by reducing power consumption compared with mid-range electrical interconnects while extending the length of data center cables.
