Looking for the best Dark Fiber providers in Littleton, Colorado? 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 are leased or sold to businesses, which then provide the necessary electronics to 'light' the fiber and enable data transmission.
Dark Fiber providers are highly dependent on geographic location due to the need for existing network infrastructure. The availability of these services is typically greater in major cities and along primary fiber lines, where the necessary infrastructure is already in place.
