2025 年全球暗纖市場規模估計為 80.6 億美元，預計到 2032 年將達到 182.8 億美元，2025 年至 2032 年的複合年成長率為 12.4%。

數字。各地區暗纖市場佔有率（%）（2025年）

暗纖是指網路供應商擁有但未積極用於資料傳輸的未使用或多餘的光纖電纜管道和網路基礎設施。這些光纖尚未使用，但可以出租給其他網路營運商或客戶。暗纖為通訊服務供應商、行動網路營運商、網際服務供應商、企業和政府提供專用高速網路容量。暗纖為新競爭者進入市場以及現有營運商在不鋪設新光纖電纜的情況下擴展其網路提供了一種經濟有效的方式。由於 5G 部署、雲端運算和網路流量不斷增加，頻寬需求不斷增加，推動了全球暗纖市場的發展。

市場動態：

由於對高速連接和頻寬密集型應用的需求不斷增加，預計全球暗纖市場在預測期內將顯著成長。主要的市場促進因素包括全球範圍內 5G 網路的不斷普及、企業的快速數位化、雲端運算解決方案的廣泛採用以及網際網路流量和行動資料消耗的不斷成長。然而，鋪設光纖電纜和安裝設備所需的高初始資本支出可能會阻礙市場成長。同時，通訊業者對光纖基礎建設的投資不斷增加，為暗纖租賃創造了巨大的機會。為了提高光纖網路的盈利，通訊業者開始租賃備用光纖作為暗纖。

Global Dark Fiber Market is estimated to be valued at USD 8.06 Bn in 2025 and is expected to reach USD 18.28 Bn by 2032, growing at a compound annual growth rate (CAGR) of 12.4% from 2025 to 2032.

Figure. Dark Fiber Market Share (%), By Region 2025

Dark fiber refers to unused or extra fiber-optic cable conduits and network infrastructure that network providers own but don't actively use for data transmission. These fibers are unused but available for leasing to other network operators or customers. Dark fiber provides dedicated high-speed networking capacity for communication service providers, mobile network operators, internet service providers, enterprises, and governments. It offers a cost-effective way for new competitors to enter the market and existing players to expand their networks without laying new fiber cables. The global dark fiber market is driven by increased demand for bandwidth from 5G deployments, cloud computing, and internet traffic growth.

Market Dynamics:

The global dark fiber market is expected to witness significant growth over the forecast period owing to the increasing demand for high-speed connectivity and bandwidth-intensive applications. Some key market drivers include the rising deployment of 5G networks worldwide, rapid digitalization of enterprises, proliferation of cloud computing solutions, and increasing internet traffic and mobile data consumption. However, the high initial capital expenditure required for laying fiber cables and equipment installation could hamper the market growth. Meanwhile, increasing investments by telecom operators in fiber infrastructure development present significant opportunities for dark fiber leasing. Telecom providers are focusing on leasing out spare fiber strands as dark fiber to make their fiber networks more profitable.
