Looking for the best Dark Fiber providers in South San Francisco in California, United States? 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 without the necessary transmission equipment, leaving the customer responsible for 'lighting' the fiber to make it operational.
Dark Fiber providers are highly location-dependent, as the availability of these unused fiber-optic cables varies by region. Proximity to major cities and existing fiber infrastructure significantly influences the feasibility and cost-effectiveness of accessing Dark Fiber services.
