Fiber Leasing & Dark Fiber Services

In a digital landscape where data is the most valuable asset, the ability to control your own network path is a massive competitive advantage.

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.

Frequently Asked Questions

What is the difference between "Lit" Fiber and "Dark" Fiber?

Lit fiber is a managed service where the provider controls the equipment and speeds. Dark fiber is the raw cable; you provide the equipment and have total control over the speed and protocol.

Who is responsible for maintenance?

CyLentrix is responsible for the physical health of the fiber cable. If there is a break or physical issue, our team handles the repair. You are responsible for the equipment used to transmit data over the fiber.

Can I lease dark fiber for a short distance?

Yes. We offer fiber leasing for local campus connections as well as long-haul regional routes.

Is it difficult to manage?

While it requires your own networking hardware and expertise, it offers a level of control that is impossible with standard internet services. Our team can also provide consulting to help you get started.
