The current research intrigue is the utilization of optical fiber in the field of PC. The universe of processing is probably going to change quickly in not so distant future on supplanting the metal wiring between parts in regular PCs with speedier and more effective fiber-optic connections. Optical fiber has enormous capacity to transport signals having bigger data, over longer separations at extremely higher speed than the connection of copper wire can do. The guideline of working of optical fiber alongside the parameters influencing and advantages of optical fiber correspondence are displayed. Constraints of Von Neumann design and metal wire interconnection in traditional PCs framework are displayed alongside how they are got calm of by utilizing fiber optics interconnection in optical PCs. Utilizations of optical strands in the field of PCs including PC system, web and optical processing are secured.
