Searching for top Dark Fiber providers in Chesterfield, MO? 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 can be leased or sold to businesses, which then install their own network electronics to create a private, high-speed network tailored to their needs.
Dark Fiber providers are highly dependent on the availability of specific network infrastructure in a given area. The closer a business is to a major city, the more likely it is to access dark fiber services. This is because the original installation of these cables was concentrated in areas with high anticipated demand, making it economically viable only in such locations.
