The literature findings were then expanded to identify patterns of changes in performance parameters due to an increase in transmission distance. transmission distance. This research focuses on fiber optik networks with different for example 5 km, 10 km and 15 km as reported in previous studies. reported in previous studies. The analysis results show that an increase in transmission distance systematically leads to a decrease in speed. data transfer rate, increased latency, jitter, and packet loss. The main factor affecting these degradations are signal attenuation, signal scattering, and interference which increase at longer transmission distances. interference which increases at longer transmission distances. This research makes an important contribution to the management of fiber optik networks, particularly This research makes an important contribution to the management of optical fiber networks, especially in the design of long-distance communication systems. Optimization strategies such as selection of high-performance components, suitable network topology planning and the application of structured Monitoring and maintenance methods are key to maintain the quality and performance of fiber optik networks.Keywords: fiber optik Network, Data Transfer Speed, Transmission Distance, Quality Network Performance]]>
