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:
“Sometimes a neighbor whom we have disliked a lifetime for his arrogance and conceit lets fall a single commonplace remark that shows us another side, another man, really; a man uncertain, and puzzled, and in the dark like ourselves.”
—Willa Cather (1873–1947)
“You will hardly know who I am or what I mean,
But I shall be good health to you nevertheless,
And filter and fibre your blood.
Failing to fetch me at first keep encouraged,
Missing me one place search another,
I stop somewhere waiting for you.”
—Walt Whitman (1819–1892)
