中國光纖因AI需求爆單
💡AI數據中心爆發引全球光纖短缺；中國供應至關重要。
⚡ 30 秒速覽
有什麼變化
美國G.657.A1光纖價自1月漲69%；歐洲兩月漲130%
為什麼重要
供應無法匹配2027年8.8億芯公里需求，AI基礎設施延遲與成本上升。超大規模業者須及早鎖定中國供應。
下一步行動
立即聯繫YOFC或亨通光電索取2026年光纖供應報價。
關鍵要點
- •美國G.657.A1光纖價自1月漲69%；歐洲兩月漲130%
- •微軟部署1.5萬公里空芯光纖；Meta投60億美元
- •中國2月出口漲126.8%；今年至4月新註冊光纖企業7607家

🔑 增強重點摘要
- •The surge in fiber demand is driving a shift toward 'hollow-core' fiber adoption in hyperscale data centers to reduce latency, as traditional silica-based fiber reaches physical limits for high-speed AI interconnects.
- •Chinese fiber manufacturers are increasingly pivoting toward specialized 'bend-insensitive' fiber production to meet the high-density cabling requirements of AI clusters, which require tighter routing than standard telecommunications infrastructure.
- •The 18-24 month lead time for preform rod production is creating a structural supply bottleneck that is forcing major cloud service providers to sign long-term 'take-or-pay' supply contracts with Chinese vendors to secure capacity through 2027.
🛠️ 技術深入
• G.657.A2 Fiber: A bend-insensitive single-mode fiber standard designed for high-density environments, offering a smaller minimum bend radius (typically 7.5mm) compared to G.652.D (30mm), crucial for AI data center racks. • Hollow-Core Fiber (HCF): Utilizes air or vacuum as the transmission medium rather than solid glass, reducing latency by approximately 30% due to the higher speed of light in air compared to silica glass. • Preform Rod Manufacturing: The critical upstream process involving Chemical Vapor Deposition (CVD) or Plasma Chemical Vapor Deposition (PCVD) to create the high-purity glass core, which currently serves as the primary production constraint.
