by optical cable
Optical cables are widely used for lighting. They are used as light-emitting diodes in medical and other fields, where bright ligthting is needed in hard-to reach places. In some buildings optical cables direct the sunlight from the roof to a certain part of the building. Optical cable lighting is also used for decorative purposes, including commercial ads and christmas trees. Optical fiber is also used to form images - the light beam passes trough lenses and is used for viewing objects trough a small hole.
Optical fiber is also used in the creation of fiber lazers.
