### AI 광케이블 증설·성장투자 (중기계획 FY26~28) (high)
- metric: Amount 530 JPY_bn · mid term FY26 28
- note: On the judgment that demand outstrips capacity, the FY26-28 plan deploys ~JPY 530bn (up to JPY 300bn for cable) to triple Japan/US capacity — a pre-emptive, demand-securing capital bet. It underwrites the FY2028 targets of JPY 1.6tn revenue and JPY 315bn OP and is double-edged: if the supercycle holds it locks in share and pricing, but if it breaks the 3x capacity becomes overbuild. What actually paces this expansion is the hydrogen/materials chain above.

### 구리·알루미늄 (전선·와이어하니스·전력케이블) (high)
- note: Copper and aluminum anchor the cost of auto wire harnesses and power cables — and are where the same input cuts opposite ways by segment: Automotive absorbs copper spikes with lagging pass-through (OP JPY 6.8bn), while Energy books copper-derivative valuation gains and grew (+58.6%). Because hedging and pass-through ability decide segment profit, copper is not a pure negative for Fujikura but a question of segment mix.

### 광섬유 프리폼 소재·수소 (실리카·GeCl4) (mid)
- note: An optical fiber begins with a preform made from high-purity silica and germanium tetrachloride plus large volumes of burned hydrogen — so the real bottleneck to expansion is materials, not tools. The filing's own warning that 'a steep ramp in optical cable could constrain procurement of some raw materials such as hydrogen' is the crux: the execution risk of the 3x-capacity plan sits in this upstream materials chain.
