Abstract As technology is becoming more valuable for our lives today, we need to have a more robust Network technology to soon sustain the latest multi-gigabit hyper-connected reality. We should have a network way faster, smoother, more reliable, and convenient than anything we've seen before — a network we call 10G. The 10G is a mix of technologies that offer symmetrical multi-gigabit Broadband access. It would just be ten times faster than today's networks and 100 times faster than most consumers usually experience, providing low latency, enhanced security, and more excellent reliability. Although 10G is a massive leap for broadband technology, the infrastructure that allows it is still under development. It is essential to track and investigate the 10G fiber optic transmission system's performance, and Wavelength division multiplexing is a way to achieve the high bitrate. Optical fiber has expanded to a wide range of applications, while the problems for long-haul communication systems and small access networks have grown in daily life. Compared to the previous decade, the demand for WDM has evolved to distribute signals over several channels and in a range with excellent signal quality. This research aims to develop a basic WDM communication system with four channels with varying channel spacings ranging from 25GHz to 100GHz and with different fiber length using the Optsim tool and comparing the system's performance without dispersion compensation and dispersion compensation using Fiber Bragg gratings. As the signal gets weaker, the quality of the signal deteriorates as the number of channels grows and the BER rises. The signal quality was enhanced, and we were able to obtain the lowest feasible BER by employing channel spacing, utilizing these channels in multiple ways as fixed and variable, and using dispersion correction.
