Looking for the best Dark Fiber providers in Southfield, Michigan? Here's your ultimate guide to making an informed choice.
What is Dark Fiber?
Dark Fiber refers to unused fiber-optic cables installed by telecommunications companies. These cables, often laid in excess during the 1980s and 1990s, are available for lease or purchase, allowing organizations to create private, high-capacity networks by installing their own transmission equipment at each end.
Dark Fiber providers are highly location-dependent, relying on the availability of existing fiber-optic infrastructure. The business case for installing fiber is strongest in densely populated or high-traffic areas, where the cost of installation can be recouped through multiple leases or high demand. In less populated areas, the high capital expenditure and ongoing maintenance costs make it less viable for providers to install or lease dark fiber.
