Searching for top Dark Fiber providers in El Paso? 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 businesses that want to manage their own network infrastructure, offering a high degree of control and customization.
Dark Fiber providers are inherently location-based, as their services depend on the availability of specific network infrastructure in a given area. The closer a business is to major cities and their connective infrastructure, the higher the likelihood of accessing Dark Fiber services. This geographical dependency makes it crucial for enterprises to consider their location when planning to adopt Dark Fiber solutions.
