Fiber Optic cable is made with glass fibers Optical engineers have found that adding different chemicals to the basic silicon dioxide they can change the optical properties of the glass. By adding approximately 4% germanium dioxide (GeO2), they can create a glass that has much less attenuation, and much 'flatter' attenuation across various frequencies of light, than silicon dioxide by itself. Fibers can be made out of either plastic or glass. The fiber optic cable used in long-distance telecommunications applications are always glass, because the optical absorption of glass is low. The light transmitted through the fiber optic cable is confined due to total internal reflection within the material. . Give very little variation in the signals Fiber optics cable carry the signals over long distances.
The fiber optic strands of glass use in fiber optic cable, carries analog or digital signals in the form of light waves. Distance and capabilities to transfer data will increase even more once the glass becomes more pure.
A fiber optic cable consists of a glass silica core through which light is guided. Its cover with a material whose refractive index of slightly less than the core. This covering is called cladding.
Usually the core and the cladding are made of high-quality silica glass, although both can be made of plastic as well.
Fiber optic cable allowing significantly higher transfer speeds compared to copper. Data transmitted in form of light pulses that is injected by a laser or an LED.
Fiber optic cable is connected by fusion splicing or mechanical splicing and requires special skills and interconnection technology due to the microscopic precision required to align the fiber cores. Fiber-optic cable is a wonderful thing; it transmits almost insane amounts of data per second, and it is not affected, magnetic fields, lightning, and all the other EM nastiest that can affect copper cable. Light is used in fiber optic cable as a communication medium.
In fiber optic cable thin filaments of glass are used and light beams are transmitted through these filaments. High information carrying capacity (bandwidth), very low error rate and insensitivity to electromagnetic interference fiber optic cable is better than copper or other cables.
Technically fiber optic cable consists of a bundle of glass or plastic rods that can transmit data signals. Fiber optic cable can send and receive both analog and digital formats, carry video, voice, and Internet transmission. Some cable designers provide built-in bend limits to protect the glass within.
Theoretical work shows that light loss in glass fibers could be decreased dramatically spurred experimental efforts to produce such fibers. Researchers continued to explore new techniques to decrease light loss in fiber optic cable.
In fiber optic cable light beam bounces off the side of the glass fibers that are thinner than a human hair. The light does not pass through the wall of the fiber, but is reflected back in and travels along to the end of the fiber.
