What are Dark Fiber and Fiber Leasing?
Dark Fiber refers to physical fiber optic strands that are “unlit” or not yet connected to active electronics. When you lease dark fiber from CyLentrix, you are renting the physical infrastructure itself. You provide your own equipment to “light” the fiber, giving you total control over the capacity, security, and technology used. This makes our solutions ideal for organizations that need high-security links, bespoke network configurations, and the ability to scale bandwidth instantly without changing their contract.
