A Performance Evaluation of 8-Channel WDM System Using Optical Amplifiers

In This paper, we have investigated the proposed 8-channel WDM system transmitted over 100 km distance is amplified with EDFA-SOA post-amplifier configuration for different EDFA length. For different EDFA-SOA combination gives different results for different EDFAs length (5m, 10m, and 15m). The proposed EDFA-SOA post-amplifier improves the input power to the receiver subsystem. Performance of hybrid amplifiers (EDFA-SOA) has been analyzed for different EDFAs lengths by Q-factor, min BER rate, threshold, and height. Also, detail analysis of the performance of both the amplifiers combination for different lengths for a WDM network shows that EDFA-SOA amplifier combination give favorable results when EDFA length is small (5m)
