1分钟科技英语：光纤

Fiber optics（光纤技术）, which transmit（传输）data via light signals through thin glass or plastic strands（细丝/股）, are the unsung backbone（幕后支柱）of AI infrastructure（基础设施）. As AI models grow larger and more complex, they require massive bandwidth（带宽）to process and transfer huge volumes of data.

Unlike traditional copper cables, fiber optics offer ultra-high bandwidth（超高带宽）and extremely low latency（延迟）, enabling real-time data transmission critical for AI training and inference（训练与推理）, such as in large language models (LLMs)（大语言模型）. Fiber optics are widely applied in AI data centers（数据中心）, edge computing nodes（边缘计算节点）, and cross-region（跨区域）AI networks. Their key advantages include high data capacity（容量）, resistance to electromagnetic interference（电磁干扰）, and long transmission distance. However, they have drawbacks（缺点）: higher initial installation costs and more complex maintenance（维护）compared to copper cables, which limits their widespread use（广泛使用）in some low-budget scenarios（低预算场景）.

Driven by the rapid development of AI, the fiber optics market for AI infrastructure is poised for（准备好/蓄势待发）robust growth（强劲增长）. Major tech firms and data center operators are increasing investments in fiber networks to support AI expansion. Industry forecasts（预测）show the market will grow steadily in the next five years, as the demand for high-speed, reliable data transmission becomes indispensable（不可或缺的）for AI advancement（进步/演进）.
