What are Fiber Optics?
Fiber-optics lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. Hundreds or thousands of these fibers are arranged in bundles called optical cables and are used to transmit light signals. The bundles are protected by the cable’s outer covering, called a jacket.
Fiber optic technology makes use of light to carry digital signals via optical cables. Fiber optic cables are very thin glass wires made from extremely pure optical glass. This technology is based on the concept of light reflection. In the case of fiber optics technology, light carrying digital signals is reflected inside the optical cable to transfer information. Total internal reflection is the principle behind the success of this technology.
Fiber optics are made of a bundle of thin glass or plastic strands. This bundle allows light to pass through without leaking out. Since the light is unable to escape, crystal clear images are passed through the fiber optics from the point of origin to the destination, where they can be viewed by the user. Fiber optics is used to create Internet data and images, images of internal organs, vocal sounds in telephones, and more than 80% of cable and satellite television images. Due to the clarity of the wiring in fiber optics, images and sounds can travel at extremely high speeds without becoming distorted at any point. In 1880, Alexander Graham Bell demonstrated how light could be used to transfer sounds from one area to another. Though it did not work on cloudy days, his discovery did set the stage for fiber optics. A few decades later, the first set of bundled fiber optics cables was developed, though it was not called “fiber optics” at the time. In 1930, a German student named Heinrich
