Searching for top Dark Fiber providers in Seattle? 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 remain unused. These cables are leased or sold to organizations looking to establish their own private networks, offering high bandwidth and enhanced security.
Dark Fiber providers are inherently location-based, relying on the existing network infrastructure in specific areas. The availability of these services is typically higher in major cities, where the infrastructure is more developed. In less urban areas, the investment required for fiber installations can be prohibitive, making access to Dark Fiber more challenging.
