Searching for top Dark Fiber providers in Columbus? Here's your ultimate guide to making an informed choice.
What is Dark Fiber?
Dark Fiber, also known as “unlit fiber” or “black fiber,” refers to fiber optic cables that have been laid by telecommunications providers but remain unused. These cables are leased or sold to enterprises for their own network needs, offering a customizable and scalable solution for high-capacity data transmission.
Dark Fiber providers are inherently location-based, relying on the existing network infrastructure in specific areas. The availability of these services is typically higher in urban centers where the infrastructure is more developed. In contrast, rural areas may face challenges due to the lack of nearby splice points and the high costs associated with new fiber installations.
