itures related to acquiring and owning properties and plants, in this case changing wires to fiber optic cables. All investment costs should be considered, such as those incurred for equipment and materials (also including storage and handling costs), engineering costs and miscellaneous costs. Operation costs include the usage of fiber optics and the wear and tear of it. The higher costs of fiber is often not by itself. Fiber optic cables are much cheaper than coaxial cables. The main difference comes when all the other components of fiber optics add up, such as transmitters, receivers, couplers and connectors. Fiber systems require separate transmitters and receivers because they cannot directly use the electrical output of computer devices; that signal must be converted into optical form and then converted back into electrical form. Fiber optic connectors and couplers are more expensive than any other electrical components. These costs are the ones that add up and form the major disadvantage of fiber optics.Conclusion:Fiber optic transmission has found a vast array of applications in computer systems. Some design considerations depend largely on the application. Forcertain terminal to terminal application, crucial factors including maximising transmission speed and distance and minimising fiber and splice loss. By contrast,connector loss becomes important in local area networks that operate within buildings. In other systems, it is important to minimise the cost of cable, with theintention of reducing the cost of terminal equipment. These system considerations make design and construction of practical fiber optic systems a difficult task.Guidelines appropriate for one system is usually not suitable for another system. There are a number of essential points about fiber optics that have been mentioned throughout this report. As we move towards a more sophisticated andmodern future, the uses of fiber optics are going to grow in all ...
