Abstract
Next generation optical networks require large capacity communication networks for proper utilization of gain bandwidth of the networks. Optical amplifiers with wavelength division multiplexed (WDM) systems are the key technologies for the realization of these networks. In this paper, we have investigated the performance of the networks using different modulation techniques, such as return-to-zero (RZ), non-return-to-zero (NRZ) and duobinary. Attempts were taken to design 8 channels, 10 Gbps WDM network at channel spacing of 0.8 nm. An innovative model with EDFA-Raman amplifier is designed to examine the performance of the different modulation schemes. From the results, it is found that NRZ configuration gives maximum output power and good quality of communication as compared to other modulation schemes. Further, it is seen that with increase in channel dispersion from 2 to 4 ps/nm/km, the quality of the signal started decreasing.
