Searching for top Dark Fiber providers in Arlington? Here's your ultimate guide to making an informed choice.
What is Dark Fiber?
Dark Fiber refers to unused fiber-optic cables that have been laid by telecommunications providers but are not currently active. These cables are available for lease, allowing businesses to create their own private networks with high bandwidth and low latency, tailored to their specific needs.
Dark Fiber providers are inherently location-based, as their services depend on the existing network infrastructure in a given area. The availability of these services is typically higher in major cities and along key intercity routes, where the necessary fiber lines are already in place.
