Searching for top Dark Fiber providers in Dallas? 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 installed by a telecommunications provider but are not currently in use. These unused cables are leased to organizations that then manage the necessary electronics to "light" the fiber, making it operational for their specific needs.
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 these unused cables is typically higher in major cities, where the connective infrastructure is more robust. This geographical dependency means that availability can vary significantly, impacting the feasibility of Dark Fiber solutions for enterprises in different regions.
