Looking for the best Dark Fiber providers in Oakland, 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 to businesses, which then install their own equipment to transmit data, giving them full control over their network's architecture, speed, and security.
Dark Fiber providers are highly location-dependent, as the availability of these services hinges on the presence of unused fiber optic cables and accessible splice points in the desired area. This means that businesses must carefully evaluate the existing network infrastructure to determine if Dark Fiber is a viable option for their needs.
