The focus of this paper is to analyze the performance of 4-Channel WDM System. The performance is analysed in terms of BER,Q-factor, eye height . Two configurations of WDM systems are used. The first one is without using EDFA and second configuration is using EDFA. For long distance transmission, EDFA plays a significant role in optical communication systems. This 4×3 Gbits/sec WDM System consist of 4 input channel transmitter, one multiplexer, one demultiplexer, and EDFA as a booster and preamplifier. In this paper, we have analysed the effect of fibre distance on 4-channel WDM System using EDFA and without EDFA in terms of bit error rate and quality factor. The analysis is done using OptiSystem 7.0 simulator. The analysis of simulation results shows that with the increase in distance the quality factor decreases and bit error rate increases.
