Searching for top Dark Fiber providers in San Diego? 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 service providers but are not currently in use. These cables were installed with the foresight that future demand for data transfer would increase, and they require the lessee to set up and maintain the electronics to "light" the fiber.
Dark Fiber providers are also location-based because they depend on the availability of a specific network infrastructure in a given area. The availability of dark fiber is higher near major cities and along major fiber lines, making it essential for enterprises to consider their geographical location when exploring dark fiber options.
