Dark Fiber

Dark fiber refers to unused fiber-optic cable. Often times companies lay more lines than what’s needed in order to curb costs of having to do it again and again. The dark strands can be leased to individuals or other companies who want to establish optical connections among their own locations.

In this case, the fiber is neither controlled by nor connected to the phone company. Instead, the company or individual provides the necessary components to make it functional.
