A dark fibre or unlit fibre is an unused optical fibre, available for use in fibre-optic communication.
The term dark fibre was originally used when referring to the potential network capacity of telecommunication infrastructure, but now also refers to the increasingly common practice of leasing fibre optic cables from a network service provider, or, generally, to the fibre installations not owned or controlled by traditional carriers.

Famous quotes containing the words dark and/or fibre:
“Traveller take heed for journeys undertaken in the dark of the year.
Go in the bright blaze of Autumn’s equinox.”
—Margaret Abigail Walker (b. 1915)
“The gods are partial to no era, but steadily shines their light in the heavens, while the eye of the beholder is turned to stone. There was but the sun and the eye from the first. The ages have not added a new ray to the one, nor altered a fibre of the other.”
—Henry David Thoreau (1817–1862)
