Looking for the best Dark Fiber providers in Marietta in Georgia, United States? Here's your ultimate guide to making an informed choice.
What is Dark Fiber?
Dark Fiber refers to fiber-optic cables installed by telecom companies that remain unused or 'unlit.' These cables, laid during the 1980s and 1990s, are now available for lease or sale, allowing businesses to install their own transmission equipment and create private, high-speed networks.
Dark Fiber providers are highly location-dependent, relying on the availability of unused fiber optic cables in specific areas. Access is often limited to major cities and their connective infrastructure, making it crucial to identify nearby splice points and work with service providers to determine feasibility.
