Looking for the best Dark Fiber providers in Leesburg, VA, USA? 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 installed but are not currently in use. These cables were often laid in excess during the 1980s and 1990s to future-proof infrastructure. Businesses can lease these unused cables and 'light' them with their own equipment to create private, high-capacity networks.
Dark Fiber providers are highly location-dependent, relying on the availability of existing network infrastructure. The closer a location is to a major city, the more likely it is to have access to dark fiber services. This is because the cost of installing new fiber is high, making it more feasible in areas where excess fiber was previously installed.
