Performance Analysis and enhancement of WDM optical networks

Abstract

In this digital era the communication demand has increased from previous eras due to introduction of new
communication techniques. As we can see there is increase in clients day by day, so we need huge bandwidth and high
speed networks to deliver good quality of service to clients. Fibre 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. It is based on
dynamic light-path allocation. Here we have to take into consideration the physical topology of the WDM network and
the traffic. We have designed here an 8-channel WDM system and carried out detailed analysis to evaluate the
dependencies of the performance evaluating parameters onto the various system parameters. This paper focuses on
design of an multi channel WDM trans-receiver System and then optimizing its performance parameters. Simultaneously
evaluation of dependencies of various performance evaluating parameters onto various system parameters was obtained.
Moreover effect of optical amplification was obtained onto system performance.
