What is a dark fiber connection?
What is a dark fiber connection?
Put simply, dark fiber is pre-existing underground infrastructure that does not yet have the hardware or software that enable it to run services. While fiber optic cables that are actively sending data via light wavelengths are considered lit, the rest of the unused fibers laying in wait are deemed unlit—or dark.
What is a dark fiber provider?
Dark fiber is fiber-optic infrastructure that is not yet “lit” or put into use by a service provider. A dark fiber lease requires the customer rather than the service provider to maintain and operate the equipment required to “light” the fiber and use it for Internet access and communications.
