Abstract. With the demands increasingly imposed by many new applications on existing networks,
long-reaching high data rate links are crucial. One of+D2
performance compared to prior studies. This paper presents a novel method to improve various system
characteristics, particularly the signal-to-noise ratio, as the main goal of improving the system's
performance in general and making it suitable to become a mainstay for networks with high data rates by
determining the optimal values for essential DWDM system parameters. To realize this, Optimization
techniques are applied to multiple critical variables such as filter bandwidth, input power, and dispersion
modulation. Optisystem program is utilized to simulate the proposed system and analyze the variables that
play a vital role in raising the performance to a higher level. Three different algorithms for dispersion
compensation and optimal power levels are also compared and implemented. The optimized scheme
proposed demonstrates the achievability of reaching long distances with a data rate of 1.28 Tbps. The
results of system performance in this study push the DWDM technique to be a candidate for high-speed
backbone optical fiber link offering an interesting practical solution for the growing network.
