Looking for the best Dark Fiber providers in Madison, Wisconsin? 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 equipment to 'light' the fiber and make it operational.
Dark Fiber providers are highly dependent on geographic location due to the necessity of specific network infrastructure. The availability of dark fiber is often greater in major metropolitan areas, where the infrastructure is more developed, making it crucial to assess the feasibility of access in your desired location.
