  • Shift: Adds the Fiber Array Unit (FAU) layer — the precision fiber↔photonic-engine coupling that becomes a low-volume-today / high-growth chokepoint as CPO moves the optical engine onto the package. This sits one layer up from the Wave-1 transceiver names, with the same "commodity-becomes-premium" shape the thesis already tracks. FOCI (3363.TWO) = the FAU leader (TSMC CPO collaborator, dominant NVDA-CPO FAU share, mass-producing 1.6T/3.2T H2 2026; MS forecasts NT$20B FAU revenue by 2028 from ~zero — secondary-reported). HIMX (NASDAQ) = exclusive wafer-level-optics (WLO) supplier to FOCI's FAUs — the one cleanly US-tradable read, added to optical-supply-chain as watch-tier. Nextronics (8147.TWO) = CPO connector/backplane layer. FOCI + Nextronics registered research-only (Taiwan TPEx, no usable US OTC proxy).
  • Effect on thesis: HOLD; additive coverage, no posture change. Carries the @vikramskr fragile-moat caveat: HIMX's WLO exclusivity is a TSMC-COUPE co-design artifact = a critical near-term CPO supplier but no durable long-term moat → a catalyst/near-term name, not a trend-hold compounder. All three ran the CPO theme then corrected (below SMA20, FOCI −33% from high, HIMX RSI 37 off a +109% 6mo run, Nextronics RSI 21) — not a trend-hold entry now.
  • Calibration: Serenity's 2026-05-18 forward-call ("next year… many articles about FAU + component bottlenecks") logged as an explicit, dated, testable 12-month entry (checkpoint ~2027-05). Outperformance of FOCI/HIMX/Nextronics over the horizon = a pre-consensus call earning @aleabit higher discovery priority; a miss = a miss.
  • Per-ticker: HIMX → watch-tier (WLO exclusivity, fragile-moat, near-term catalyst not compounder); FOCI → research-only (FAU leader, highest thematic priority but untradable); Nextronics → research-only (connector layer, oversold).
  • Open (non-blocking): MS NT$20B FOCI FAU note (paywalled — cited secondary); HIMX 20-F WLO-segment breakdown; Nextronics 2025 annual; calendar catalyst = H2 2026 FOCI 1.6T/3.2T FAU mass-production ramp confirmation.
