From the beginning, speed and efficiency in the telecommunications business has advanced at a fast rate because of fiber optic technology. In 1979, AT&T filled the telecommunications business with revolutionary ideas by creating a style for data transmission by means of a mild, called fiber optic cable. This mode produced a bandwidth of 44.736 Mbps and may multiplex 672 trunk circuits onto one fiber (Cole, M. 2000). However, this development was only the start of a massive extension to telecommunications, something which would change the sector constantly. Though AT&T brought in fiber optic technology in 1979, they were not the first organization to think of such a creative thought. The concept of interchanging data by making use of light has been the concept of by Alexander Graham Bell in 1800s. Bell always thought of this prospective that stimulation of light can move voice signals, but on no account Bell needed a reliable light source to experiment to the idea (Cheo, P. 1990). In 1880, Bell patented - that the Photophone--a phone which operates by means of optical transmission. Unfortunately, Bell's innovation was of no success for the reason that it applies atmosphere as the mode of transmitting light instead of the glass fibers that are applied now. Copper cable was essentially more reliable than Bell's apparatus in the stage, causing his Photophone to fail (Hecht, J. 1999). Elaborating on Bell's concept, John Logie Bard, a British scientist, and Clarence W. Hansell, an American scientist, patented the design using empty glass pipes to carry television scenes from the 1920s. Still, the tubes optimized were under standard and failed signal failure very easily. Bard and Hansell also stumble upon exactly the same problem Bell had, maybe not becoming a steady,.
