From the beginning, efficiency and speed in the telecommunications industry has advanced at a fast pace owing to fiber optic technology. In 1979, AT&T filled the telecommunications industry with revolutionary ideas by developing a mode for data transmission using a light, called fiber optic cable. This mode produced a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits on one fiber alone (Cole, M. 2000). However, this development was merely the start of a huge extension to telecommunications, something that would transform the industry constantly.
Although AT&T brought in fiber optic technology in 1979, they weren’t the first company to think of such a creative idea. The conception of interchanging data by making use of light

The laser was small in size than a grain of sand, but the application of fiber optics in telephony was made possible. In 1987, an additional accomplishment in the fiber optics industry was fulfilled; this accomplishment was the erbium-doped fiber amplifier, which admitted numerous channels of light to coexist on a single circuit. This fiber amplifier rendered sufficient channels for single fiber cable to manage 80 million telephone calls at the same time (Greatest Achievements, 2000).
Nowadays, fiber optic technology carries data by distributing light pulses along slim strands of plastic or glass fiber by means of a laser or light emitting diode (LED). Strands of fiber are comprised of three major components: the core, cladding, and buffer coating. The contained by part of the fiber is called the core. A fiber’s core is the pathway where the light passes through. Encompassing the core is optical matter called cladding. Cladding recurrently reflects light pulses stimulating the pulses to pass through easily by way of the fiber core. The buffer coating functions as a covering for the cladding and the core by shielding it from external elements, for example, moisture (Fotec, 1996).
The glass fibers that constitute the core of the fiber strands employed in contemporary fiber optic systems are generally established on pure sand. Fiber created from regular glass utilized in windows is polluted that impurities
