SemiAnalysis Report Claims Delay in Two Key Technologies, Triggers Sharp Decline in 'Optoelectronics', Sparking Online Debate Over CPO

A report from analysis firm SemiAnalysis, claiming significant delays in two key AI data center technologies, triggered a sharp sell-off in the photonics sector and sparked intense online debate. The report, dated June 10, states that NVIDIA's 800VDC power architecture rollout is pushed to 2028 and CPO (Co-Packaged Optics) mass production is likely delayed until 2028 or even 2029. Following the news, U.S. optical communication stocks fell sharply, with AAOI dropping 17% and Lumentum down about 8%. The delays were attributed to engineering challenges like photonic engine yield and cost-effectiveness, not a disappearance of demand. Simultaneously, an interview with NVIDIA's networking SVP Gilad Shainer presented an opposing, optimistic view, stating CPO is "the most exciting thing" and shipments would begin scaling in the second half of the year. This contradiction fueled debate on social media. Bears pointed to unresolved reliability and maintenance hurdles for CPO. Bulls argued the delay simply redirects capital to interim solutions like traditional pluggable optical modules and NPO (Near-Packaged Optics), extending their revenue runway. Some users questioned the report's internal logic and timing, noting similar views had circulated earlier. Analysts highlighted potential beneficiaries, including companies in the 1.6T pluggable modules, NPO, and 400VDC power transition supply chains. The consensus suggests the market reaction reflects a recalibration of the technology adoption timeline rather than a fundamental weakening of AI infrastructure demand, with key bottlenecks like power, storage, and GPUs remaining unchanged.
