Looking for the best Dark Fiber providers in Alpharetta, Georgia? 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 cables are leased to businesses, which then install their own equipment to transmit data via light pulses, giving them full control over the network's architecture and performance.
Dark Fiber providers are highly location-dependent, as the availability of these unused fiber optic cables varies by region. Access to Dark Fiber requires existing infrastructure, such as unlit strands and accessible splice points, which are more common in densely populated areas and major cities. This makes the feasibility of Dark Fiber services contingent on the specific network infrastructure in a given area.
