So far this year, 800VDC (800-volt direct current) and CPO (co-packaged optics) have undoubtedly been the two dominant narratives driving the semiconductor market.
However, a report released overnight by the well-known AI supply chain research firm SemiAnalysis caught the market off guard. The report directly stated that these two core technological pathways for AI data centers will face delays: $NVIDIA (NVDA.US)$ Shipments of the 800VDC power architecture are now expected to be delayed until 2028, while mass production of CPO may be pushed back to 2028 or even 2029.
The simultaneous downward revision of these two key expectations instantly triggered violent volatility in the optical communications sector and ignited heated debates across the industry and capital markets about future technology roadmaps and investment opportunities.
So, what signals does SemiAnalysis’s report actually convey to provoke such intense market panic? Is this a substantive bearish development driven by shifting industry fundamentals, or merely indiscriminate overselling fueled by emotional reaction? This article will break it down for fellow investors, cutting through the noise to clarify future investment directions.
I. The Report at the Eye of the Storm: Why Are Both Key AI Technologies Facing Delays?
In this report, SemiAnalysis presented two core conclusions with potentially disruptive implications for the market.
1. 800VDC Architecture: Delayed until 2028; ±400VDC remains on track
