Simulative Investigation of Laser Line-width and Channel Spacing for Realization of DWDM Systems under the Impact of Four Wave Mixing

Abstract This work is focused on how to implement 4- and 8-channel dense wavelength division multiplexing (DWDM) system, with each channel of 10 Gbps over an optical span of 100 km in the presence of four wave mixing (FWM) under the impact of unequal-channel spacing and laser line-width. In this proposed work, we have evaluated electrical power, Q-factor and average eye opening of 4- and 8-channel dense wavelength division multiplexing in the presence of FWM under the impact of equal channel spacing of 0.24 nm and 0.27 nm at 100 kHz, 10 MHz and 100 MHz laser line-widths. The comparison of parameters in the terms of electrical power, Q-factor and average eye opening has been observed at different laser line-widths.
