1.8;margin-bottom: 24px;"><span leaf=""><span textstyle="" style="font-weight: bold;">资本市场重估</span>:光通信板块被视为AI产业链中斜率最高、确定性最强的领域之一。例如,美国公司Applied Optoelectronics(AAOI)在2026年初股价一度上涨超300%,市值突破120亿美元,反映了市场对AI互联需求的极度乐观。</span></section><h1 data-layout-id="6" style="font-size: 20px;font-weight: 500;color: rgba(42, 174, 103, 1);line-height: 1.8;margin-bottom: 12px;text-align: center;"><span leaf="">二、 核心驱动力:世界模型与智能体(Agentic AI)创造“算力黑洞”</span></h1><section data-layout-id="7" style="font-size: 17px;font-weight: 400;color: rgba(0,0,0,0.9);line-height: 1.8;margin-bottom: 24px;"><span leaf="">AI技术本身的进化,特别是“世界模型”的实用化,是本次算力革命的核心变量。</span></section><section data-layout-id="8" style="font-size: 17px;font-weight: 400;color: rgba(0,0,0,0.9);line-height: 1.8;margin-bottom: 24px;"><span leaf=""><span textstyle="" style="font-weight: bold;">世界模型的需求</span>:如腾讯的混元3D世界模型2.0和英伟达的Cosmos模型,要求AI能够模拟和理解物理世界,进行三维重建与交互。这种多模态、复杂几何计算使得单次模型训练消耗的算力达到千万GPU小时级别,呈指数级增长。</span></section><section data-layout-id="9" style="font-size: 17px;font-weight: 400;color: rgba(0,0,0,0.9);line-height: 1.8;margin-bottom: 24px;"><span leaf=""><span textstyle="" style="font-weight:
