Looking for the best Dark Fiber providers in St. Louis, Missouri? Here's your ultimate guide to making an informed choice.
What is Dark Fiber?
Dark Fiber refers to fiber-optic cables installed by telecommunications companies that are not currently in use. These unlit cables are available for lease or sale, allowing businesses to create their own high-speed, private networks by providing the necessary equipment to 'light' the fiber.
Dark Fiber providers are highly dependent on location due to the need for specific network infrastructure. The availability of dark fiber is greater near major cities and along key routes, where existing fiber lines and splice points are more common. This infrastructure dependency means that access can be limited in less urbanized areas.
