Performance Analysis of 48 Channels DWDM System using EDFA for Long Distance Communication

Dense wavelength division multiplexing (DWDM) is an advance technology. Optical fiber communication technology is used to send data in long distance. In this work to calculated the performance and analysis of Dense Wavelength Division Multiplexing. And also evaluate the quality factor and bitrate of optical pulse. Different mode of optical fiber used to send the data. Here SMF (Single mode fiber) and DCF (dispersion compensation fibers) are used. This work focuses on the 48 channel DWDM with described looping particularly explained by the BER analyzer and the Optical Analyze. Optical Add/Drop Multiplexers (OADMs) are used in wavelength-division multiplexing systems for routing fiber optic signals and multiplexing, it is used to transmit the data in long distance communication. In this method two modulation technique can be used RZ and NRZ .in this work NRZ modulation method can be used.
