Data Center Interconnect & Dark Fiber

Data Center Interconnect & Dark Fiber covers the high-capacity fiber connections between data centers and the leasing of unlit ("dark") fiber that customers light with their own equipment. It is the connectivity fabric linking data-center campuses, cloud regions, and network hubs, served by fiber operators and dark-fiber specialists (Zayo, Lumen, and metro-fiber providers).

Demand is propelled by cloud computing, the AI-driven data-center boom, and the need for massive, low-latency bandwidth between facilities, with dark fiber prized by hyperscalers and large enterprises wanting dedicated capacity and control. It is consolidating around scaled fiber platforms and a high-growth, infrastructure-investment-active segment tightly coupled to the data-center build-out.
