Looking for the best Dark Fiber providers in Doral, Florida? 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 by companies, who then provide their own transmission equipment to 'light' the fiber and create a high-speed, private network.
Dark Fiber providers are highly dependent on the availability of specific network infrastructure in a given area. The physical fiber cables must already exist underground, and there must be unused strands available for lease. This makes the service more accessible in or between major metropolitan areas where the infrastructure investment can be more easily justified.
