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:
“My beautiful, my beautiful! That standest meekly by,
With thy proudly-arched and glossy neck, and dark and fiery eye!”
—Caroline Sheridan Norton (1808–1877)
“One of the oddest features of western Christianized culture is its ready acceptance of the myth of the stable family and the happy marriage. We have been taught to accept the myth not as an heroic ideal, something good, brave, and nearly impossible to fulfil, but as the very fibre of normal life. Given most families and most marriages, the belief seems admirable but foolhardy.”
—Jonathan Raban (b. 1942)
