June 10th, Herman Jin (@ShanghaoJin), a KOL covering the US stock market, responded to the claim that "only Intel’s (INTC) EMIB packaging technology can truly achieve Co-Packaged Optics (CPO), while TSMC’s CoWoS technology cannot." Jin commented, "Currently, CPO faces severe capacity bottlenecks and widespread yield issues. Let’s stay level-headed for now and avoid being overly optimistic."

June 10th – U.S. President Trump stated that Iran shot down a U.S. Apache helicopter in the Strait of Hormuz, and that the U.S. must provide a necessary response to the attack, per FXStreet.

June 10: Per Bitget market data, the U.S. optoelectronic module sector suffered a broad sell-off today, with leading players’ shares plummeting: Marvell Technology (MRVL) dropped 13.3%, Applied Optoelectronics (AAOI) fell 16.4%, Nokia (NOK) declined 8.5%, Lumentum (LITE) slid 11.77%, and Coherent (COHR) dipped 15.2%. BlockBeats previously reported that SemiAnalysis—an independent research firm focused on semiconductors, AI infrastructure, and data centers—published a new cross-vertical research note today. Its key conclusion directly flags significant delays in shipments for two critical technologies powering AI data centers: NVIDIA’s native 800VDC architecture, and the mass production delivery of Co-Packaged Optics (CPO).

June 10 — Independent research firm SemiAnalysis, a leading analyst focused on semiconductors, AI infrastructure, and data centers, released its latest multi-vertical research note today, with a core takeaway pointing to significant delays for two key AI data center technology paths. First, NVIDIA’s native 800VDC architecture shipments are being pushed back sharply. The report states NVIDIA’s originally planned single-ended 800VDC power supply design, intended for broad industry adoption, now has a shipment window extended to 2028. While the 400VDC high-voltage direct current solution remains on track, hyperscalers are choosing to stick with mature low-voltage systems or make gradual transitions to 400VDC rather than rushing to adopt 800VDC. The firm notes the marginal benefits of 800VDC for grid power and efficiency improvements don’t justify its added complexity, leading to a temporary industry slowdown for this tech. Second, the timeline for CPO (Co-Packaged Optics) mass productio
