研究:2025年光纤占1065000万美元数据中心线缆市场的47.6%
DC Market Insights于2026年10月6日发布的一项研究显示,2025年光纤光缆占1065000万美元数据中心线缆市场的47.6%。AI机房每兆瓦的布线支出是传统机房的两倍多。

该研究估算,2025年面向AI的数据机房每兆瓦布线成本约为1.07百万美元,传统机房约为0.43百万美元。研究预测,到2035年线缆市场总规模将达到2729000万美元,年复合增长率为9.87%。上述数字均为该公司的估算和预测。
AI机房为何用更多光纤
研究指出,GPU集群依赖连接大量加速器的高容量后端网络,其光纤数量远超传统企业或云环境。在某些AI机柜配置中,机柜间连接的光纤可超过3000根,因为400G、800G以及新兴的1.6T架构缩短了铜缆的实际传输距离。
铜缆的局限在于距离和散热。Tech Times报道称,在每通道200 Gb/s的速率下,无源铜缆已无法在一个服务器机柜内稳定传输而不出现信号衰减和过热。EE Times认为铜缆的通常上限是100米,超过这一距离,衰减和串扰就成为主要障碍;而商用光纤链路通常可达400-800 Gbps,先进的光互连可在数公里距离上达到1.6 Tbps。
光纤的市场份额
光纤2025年收入为507000万美元,预计到2035年将增至1594000万美元,年复合增长率为12.14%,快于整个市场9.87%的预测增速。铜缆占2025年收入的31.4%,电力电缆占21.0%,光纤仍是最大的单一类别。
与它所服务的设施相比,线缆市场并不大:EE Times报道称,2025年数据中心资本支出将接近2500亿美元,并援引对超大规模厂商的调查称,到2025年底,约85%的新建骨干部署将采用光纤而非铜缆。
谁在买线缆
研究发现,超大规模数据中心是2025年最大的买家类别,贡献约495000万美元,占需求的46.5%。托管数据中心占25.3%,企业数据中心占18.4%,GPU和neocloud供应商占9.8%。但最小的这一类增长最快,预计到2035年其支出的年复合增长率为12.21%。
高速以太网和GPU网络连接2025年约占292000万美元,预计到2035年将达到104亿,并在本十年结束前超过传统网络连接。
研究的预测
2025年AI设施约占新增容量的35%,研究预测这一比例到2035年将达到66%。研究模型显示,年度新增IT容量将从2025年的约12.0 GW升至2035年的27.0 GW,2025年新建项目约占线缆支出的73.8%。
研究还指出,大型超大规模厂商和连接供应商越来越多地在数据中心园区投运前数年就锁定光纤产能,从而降低供应不确定性,并支撑制造产能扩张。
