微软联手康宁、贺利氏扩产空芯光纤

讯石光通讯网2025-09-25

ICC讯为更好地支持AI工作负载，微软正加速推进空芯光纤的全球部署。这家科技巨头已与康宁（Corning）及德国供应商贺利氏科维克公司（Heraeus）达成协议，旨在构建"跨国生产供应链，以规模化生产下一代光纤"。微软在其博客中宣布了这一动向。空芯光纤与传统单模光纤的区别在于，其通过内部充满空气的空心通道而非实心玻璃来传输光信号。支持该技术的人士认为，由于光在空气中的传播速度比玻璃中更快，空芯...

Lathrop在LinkedIn上评论指出，熔接空芯光纤需要\"高度专业化的设备\"，而这些设备尚未普及。此外，他表示运营商目前缺乏专门针对空芯光纤培训的外部工厂团队，且空芯光纤的抗压和抗拉耐受度均低于单模光纤。  Lathrop补充道，目前用于测试和维护光纤网络的光时域反射仪\"无法检测空芯光纤内部的湿气、灰尘或断裂——所有这些都会损害传输性能\"。  原文：Microsoft preps
