Looking for the best Dark Fiber providers in Sacramento, California? 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 laid by telecommunications providers but are not currently in use. These cables are leased or sold as core network services, with the customer responsible for installing the necessary electronics to make the fiber operational.
Dark Fiber providers are highly dependent on the availability of specific network infrastructure in a given area. The presence of unused, unlit fiber optic cables and accessible splice points determines whether Dark Fiber can be offered, making it more prevalent in densely populated or high-traffic regions.
