What are Optical Fibers?What are Optical Fibers?
Long thin strands of very pure Long thin strands of very pure glass about the diameter of a glass about the diameter of a human hair.human hair. They are arranged in bundles They are arranged in bundles called optical cables and used called optical cables and used to carry digital information to carry digital information over long distances.over long distances.Used heavily in Used heavily in telecommunications and telecommunications and computer networkscomputer networksAlso used in medical imaging Also used in medical imaging and mechanical engineering and mechanical engineering inspection inspection
