A Full List of Dark Fiber Providers in Boston

Searching for top-notch Dark Fiber providers in Boston, Massachusetts? 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 are not currently in use. These unused cables are leased to businesses, which then install their own equipment to 'light' the fiber and create a high-speed, private network.

Dark Fiber providers are highly location-dependent, relying on the availability of existing, unused fiber optic cables in a given area. Proximity to major cities increases the likelihood of access, as urban centers typically have more extensive fiber infrastructure. However, outside these areas, the availability can be limited due to the high costs associated with laying new fiber and creating new splice points.
