In this digital era the communication demand has increased from previous eras due to introduction of new communication techniques. As the authors can see there is increase in clients day by day, so they need huge bandwidth and high speed networks to deliver good quality of service to clients. Fiber optics communication is one of the major communication systems in modern era, which meets up the above challenges. This utilizes different types of multiplexing techniques to maintain good quality of service without traffic, less complicated instruments with good utilization of available resources. Wavelength Division Multiplexing (WDM) is one of them with good efficiency.
