Abstract
This paper examined the impact of chirped fiber Bragg gratings (CFBGs) on the 16 × 20 Gbps DWDM system’s performance. An approach to compensate dispersion in a 16 × 20 Gbps DWDM system over a 100 km conventional fiber is employed that comprises cascaded chirped fiber Bragg gratings. To get the highest Q factor for every channel, the gratings are optimized in terms of apodization strength, chirp parameter, and grating length. By changing the input power per channel from 0 dBm to +12 dBm, the impact of the nonlinear FWM effect in our suggested system is examined. For all channels, an average Q factor of 15.11 was achieved at an input power of +10 dBm. Even at high input power (+12 dBm) for all 16 channels, the average Q factor is above the predetermined threshold of 6, demonstrating the effectiveness of the configuration for simultaneous dispersion compensation and high tolerance to nonlinear effect.
