Looking for the best Dark Fiber providers in Birmingham, Alabama, United States? 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 are not currently in use. These unused cables are leased or sold to businesses, which then install their own equipment to 'light' the fiber and make it operational.
Dark Fiber providers are highly dependent on the availability of specific network infrastructure in a given area. The presence of unused, unlit fiber optic cables and proximity to splice points are crucial factors that determine whether Dark Fiber services can be offered. This location-based nature means that access to Dark Fiber is often more feasible in areas close to major cities or existing fiber lines.
