This paper has evaluated the performance of 120 channels dense wavelength division multiplexing (DWDM) system with power amplification from erbium-doped optical fiber amplifier (EDFA). Further, analysis has carried out with considering the varied channel spacing (0.9 nm to 0.1nm), varied communication distance (20 km to 120 km), and varied transmission data rate (6 Gbps to 16 Gbps) to maintain the required bit error rate (BER). Final analysis has recommended that transmission data rate of 6 Gbps is the suitable choice for varied channel spacing with EDFA to deliver the required signals characteristics, while rest of the transmission data rates has shown the worst response with decreasing the channel spacing.

Abstract


This paper has evaluated the performance of 120 channels dense wavelength division multiplexing (DWDM) system with power amplification from erbium-doped optical fiber amplifier (EDFA). Further, analysis has carried out with considering the varied channel spacing (0.9 nm to 0.1nm), varied communication distance (20 km to 120 km), and varied transmission data rate (6 Gbps to 16 Gbps) to maintain the required bit error rate (BER). Final analysis has recommended that transmission data rate of 6 Gbps is the suitable choice for varied channel spacing with EDFA to deliver the required signals characteristics, while rest of the transmission data rates has shown the worst response with decreasing the channel spacing.
