Looking for the best Dark Fiber providers in Fresno, 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 unused cables can be leased or sold, allowing businesses to establish their own high-speed, private networks by installing and maintaining the necessary equipment to transmit data.
Dark Fiber availability is highly dependent on geographic location and existing network infrastructure. The closer a business is to a major city, the more likely it is to access dark fiber services. However, even proximity to a major fiber line does not guarantee access, as connections are made via splice points, and carriers may be reluctant to create new splices.
