Design and analysis Wavelength Division Multiplexing (WDM) system with Erbium-doped Fiber Amplifier (EDFA)

Abstract

Optical fiber communication system nowadays is a fast growing mechanism to sent information signal. Unfortunately there are several limitation that makes the data signal that been sent unreliable. These problems are more severe when sending information signal over long distance. The main objective of this project is to study and analyse the effect of EDFA in WDM system. Basically this project consists of calculation, design and simulation using simulation software called OptiSystem 6.0. From the calculation, we know the required gain for EDFA for a particular design system of using communication link. This is called link budget analysis. While simulation part shows that the calculation before is correct hence to analyse the effect of EDFA in WDM system. Other than that, this project also analyses the noises that occur in system. A simulation tool called OptiSystem 6.0 is practical and reliable software to design and analyze the WDM system design. The design must as close as possible to the real situation. Some parameters has been considered in order to see the output result like design parameters and performance parameters.
