Searching for top Dark Fiber providers in Pittsburgh, Pennsylvania? 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 unused cables, laid by telecom companies in anticipation of future demand, are leased or sold to organizations that need high-capacity, private network connections.
Dark Fiber providers are highly location-dependent, relying on the availability of existing, unused fiber-optic infrastructure. The closer a business is to a major city, the more likely it is to access these services, as fiber lines typically run between urban centers. However, even proximity to a major fiber line doesn't guarantee access, as connections are made via specific splice points.
