A Survey of Optical Interconnects for Next-Generation Intelligent Computing Centers:Architectures,Key Technologies,and Challenges
摘要
Abstract
The development of generative artificial intelligence and Large Language Models(LLM)has driven the continued scal-ing of distributed training.Therefore,communication overhead has emerged as a major performance bottleneck,shifting the sys-tem constraints from computation to network connectivity.Traditional electrical interconnects are increasingly limited by band-width-distance tradeoffs,energy efficiency,and scalability,making them insufficient for large-scale synchronized data exchange.In contrast,optical interconnection technologies,with their high bandwidth density,low latency,and topological reconfigurabili-ty,provide a promising solution to these challenges.Accordingly,this paper systematically reviews the key architectures and core technologies of optical interconnect networks for intelligent computing centers and discusses future development trends.关键词
