If you mean Fiber Optics, then those are used to transmit data usually on a DSL line, to the ISP and back to you.

Optic Fibers
It is a true statement that fibers of the optic nerve synapse at lateral genticulates of the thalamus.
Yes
Yes, in fact they are used more and more, for high-speed data transmission.
In fiber optic communcations Dark Fiber or Unlit Fibers refers Unused fibers, available for use
Each eye contains an optic nerve, as the meet at the optic chiasm, some of the nerve fibers cross over. This sensitive area is referred to as the optic nerve pathway crossover.

optic (II)
Approximately 20% of the optic nerve fibers are responsible for the light reflex. These fibers are involved in transmitting the signal from the retina to the brain to regulate the constriction of the pupil in response to changes in light intensity.
Optic nerve have no branches.Any way fibers from optic nerve ultimately reaches visual cortex(occipital lobe).
Photoreceptor cells in the retina. Bipolar cells in the retina. Ganglion cells in the retina. Optic nerve fibers in the optic nerve. Lateral geniculate nucleus in the thalamus. Optic radiation fibers in the brain to the primary visual cortex in the occipital lobe.
