Dark Fiber Market 2025 Research Analysis, Strategic Insights and Forecast to 2033
Dark Fiber Market 2025 Research Analysis, Strategic Insights and Forecast to 2033
Dark fiber refers to unused or underutilized optical fiber infrastructure that has been laid but is not currently active or “lit.” Originally installed by telecom operators in anticipation of future demand, dark fiber is now increasingly leased to enterprises, government agencies, ISPs, and data centers for private, scalable, and high-bandwidth communication networks. The market is gaining traction due to rising data traffic, cloud computing, 5G deployment, and cybersecurity concerns.
The global dark fiber market was valued at USD 5.95 billion in 2022, increasing at a CAGR of 11.15% from 2022 to 2030 and is anticipated to reach USD 13.85 billion by 2030. Further, the COVID-19 pandemic has positively influenced the growth of the global dark fiber market.
