Goldman Sachs has designated optical networking as the next critical bottleneck in AI infrastructure, projecting a 9x growth opportunity valued at $154 billion. The firm's analysts argue that surging demand for high-speed data transmission between AI data centers is outstripping current optical fiber and component capacity, creating a looming supply crunch.
The catalyst stems from the explosive scaling of AI workloads. As large language models and training clusters require exponentially more bandwidth, traditional copper-based interconnects are hitting physical limits. Optical networking—using light pulses through fiber optics—offers dramatically lower latency and higher throughput, making it essential for next-generation AI clusters. The bank noted that the shift is already accelerating as hyperscalers race to upgrade their backbone infrastructure.
Three companies were highlighted as key beneficiaries: Coherent Corp., Lumentum Holdings, and Fabrinet. Shares of all three ticked higher in early trading following the report. Quanta Services, a data center power and infrastructure firm, also traded within a buy zone after being named a stock of the day by IBD, reflecting broader investor appetite for AI-enabling industrial plays.
A counterargument is that optical component suppliers have historically suffered boom-bust cycles, and current valuations may already price in years of growth. Analysts caution that execution risks—from supply chain constraints to technology shifts—could derail the timeline for this megatrend. The report does not specify a timeframe for the 9x projection.
