Looking for the best Dark Fiber providers in North Charleston in South Carolina, 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 cables lack the necessary transmission equipment to 'light' them, leaving the responsibility of setting up and maintaining the electronics to the customer.
Dark Fiber providers are highly location-dependent, as access to these unused fiber strands relies on the presence of specific network infrastructure in the area. Availability is typically greater in major cities and their connecting lines, where dense, pre-existing fiber networks are more common.
