Looking for the best Dark Fiber providers in Waterloo, ON, Canada? 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 but are not currently in use. These unused cables can be leased or sold to businesses, which then install their own network equipment to 'light' the fiber, creating a private, high-speed network tailored to their needs.
Dark Fiber providers are highly location-dependent, relying on the availability of specific network infrastructure. The service is most viable in urban areas with dense, pre-existing fiber installations, while rural or less-connected regions may face challenges due to the high costs and complexities of new fiber installations.
