Searching for top Dark Fiber providers in Berlin, Germany? 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 installed by telecom companies but are not currently in use. These unused cables are leased or sold, allowing businesses to 'light' the fiber with their own electronics to create a WAN link, giving them full control over the network's architecture, speed, and security.
Dark Fiber providers are highly dependent on geographic location due to the need for existing, unused fiber-optic infrastructure. The availability is typically higher in major cities and along routes connecting them, where demand and potential revenue justify the investment. In less populated areas, the high costs of installation and maintenance make it less feasible for carriers to offer Dark Fiber services.
