What is Dark Fiber?

“Dark Fiber” or sometimes spelled as “Unlit Fiber” is defined as being an unused optical Fiber cable or networks, which are usually used in Fiber-optic communication. This cable, or group of cables, may be set in place, but they are usually not being used at the current time.

All About Dark Fiber

In modern times, the term “dark Fiber” is now used to discuss the ever-growing, standard procedure of leasing out Fiber optic cables from a network provider/service provider, or, out to the Fiber installation/Fiber infrastructure that isn’t owned by regular carriers. Dark Fiber can still be called “dark”, even if it has been utilized by a Fiber lessee and not by the original owner of the cable.
