Abstract

The focus of this paper is to investigate a 40 Gbit/s DWDM system over the optical span of 100 km in the presence of Four Wave Mixing (FWM) under the impact of equal channel spacing at varied values of laser line-width. In this proposed work, the performance of DWDM system is carried out by evaluating received electrical power, Q-factor and average eye opening at varied values of equal channel spacing of 0.26 nm and 0.24 nm at laser line-widths of 100 kHz, 10 MHz and 100 MHz under the impact of fiber dispersion.
