Searching for top Dark Fiber providers in Phoenix? 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 organizations that wish to manage their own network infrastructure, offering a customizable and scalable solution for high-capacity data transmission.
Dark Fiber providers are inherently location-based, as their services depend on the availability of specific network infrastructure in a given area. The presence of unused fiber cables and proximity to splice points are crucial factors, making it more feasible in urban areas with established connectivity.
