Analysis of EDFA-WDM Optical Network System

Abstract

In WDM systems optical fibers are utilized to transmit data in type of light pulse between the transmitter and the receiver. WDM frameworks can possibly transmit multiple signals at the same time. However, the light signal decreases in power when they travel a long distance inside the fiber. So it is required to intensify all the light signals at the same time after a specific interval of light spread to recover the first signal. Optical amplifiers are for the most part used to regenerate the light pulses. There are numerous optical amplifiers. One of the normal amplifier utilized is Erbium Doped Fiber Amplifier. In this paper the investigation of WDM system is done on the basis of Erbium Doped Fiber amplification and dispersion compensation mechanism utilizing Optisystem programming.
