1月26日，长飞光纤光缆港股涨超16%，A股涨停。
消息面上，根据光电通信公众号，2025年第四季度长期作为市场主流的G.652.D普通光纤出现显著的价格上涨与供应紧张，且部分大厂库存已无法满足自身订单，开始转向外采。光纤光缆行业需求结构发生变革。甬兴证券认为，随着AI算力网络、6G预研、全球数字基建等需求的持续释放，全球光纤光缆市场有望进入2～3年的高景气周期。维持通信行业“增持”评级，建议关注光纤光缆相关投资机会。
开源证券此前研报指出，随着全球AI蓬勃发展，或持续驱动数据中心内部与DCI互联对光纤光缆的需求，短期来看，全球厂商扩产能力有限，或将形成供不应求的格局，该行认为光纤光缆需求和价格有望维持稳步提升。
