Design and Optimization of a Multi-Core Fiber Optic Communication System for High-Capacity Data Transmission in Iraq’s Urban Environment

Iraq's industry has gone through various transformation phases and has seen tremendous growth during the recent years. To sustain such growth, the infrastructure should be highly efficient. Fiber optic technology is a main component in the networks because it provides high bandwidth and high speed, thus providing support for current and emerging technologies. To the best of our knowledge, various research works carried out in Iraq so far have not touched on the point of effective improvement in the performance of the fiber optic communication system. The concept behind this research is the design of a Radio over Fiber system using the Optisystem simulator, focusing on how to improve the performance of a multi-core fiber optic communication system by improving the transmission capacity and enhancing the reception system to raise the quality of the received signal and obtain a lower bit error rate. The simulation results showed that there was much enhancement in the quality of transmission, reducing the bit error rate by 10 times in comparison with previous systems while providing better signal clarity. These improvements are in line with recent advances in optical fiber technology used in similar studies globally.
