Analysis of EDFA Parameters Amenable for Ultra High Bitrate Based DWDM System

Abstract

Exponential growth in data centric services often leads to overhaul of backbone and access networks. Design of high transmission capacity of up to 640Gbps DWDM system with EDFA was analyzed to meet less distortion in an optical backhaul system. Further the length of EDFA and pump power of EDFA are varied and evaluated for 16, 32 and 64 channels data transmission efficiently, such that it caters to the requirements of access networks. Parameters such as pump power and length of optical Amplifier in DWDM system are studied and its output characteristics are analyzed from co-channel and counter-channel propagations. The dependences parameters such as maximal BER, minimal SNR values among all the channels with signal power detection for each pump power results are obtained and compared to the same. Evaluations of Quality factor and BER for each pump power with all three configurations were done for different lengths of EDFA. The DWDM system with suggested optimum EDFA parameters gives good results in terms of Q-factor, eye opening and BER.
