The article presents an examination of the quality control of fibre optic networks through measurement-based analysis. In addition to outlining the fundamental components of fibre optic networks, the article details the employed measurement methodology, data processing techniques, and the subsequent analysis of the obtained results. Based on a case study, a specific network was examined, the results were analysed and targeted recommendations for quality enhancement were proposed. Utilising Optical Time-Domain Reflectometry (OTDR), network anomalies such as signal interruptions, reflections, and attenuation, were identified and corrected. This method provides a detailed insight into attenuation variations along the entire fibre length, facilitating the precise localisation of issues such as microfractures or suboptimal connections. The findings demonstrate that corrective actions—such as replacing compromised fibre segments and optimising connector interfaces—can significantly reduce signal degradation and enhance overall network stability. Furthermore, the analysis encompasses a network architecture composed of multiple components designed to support a robust and high-quality transmission system. The network utilises a tree topology which allows efficient signal distribution from a single central source node to multiple endpoints, with the flexibility to incorporate additional branches as needed.
