This scientific research investigates the mechanisms of signal loss and reflection in bent optical fiber routes and analyzes their impact on the efficiency of radio direction-finding systems based on numerical and experimental data. The study revealed that at bending angles from 30° to 90°, signal loss increased from 0.05 dB to 0.25 dB, and the reflection coefficient rose from 1.2% to 4.8%, leading to a decrease in system sensitivity from 95.4% to 81.7%. Engineering solutions proposed include the use of bend-insensitive fibers, maintaining a minimum bending radius of the route, OTDR monitoring, and integration of regenerators. Additionally, channel capacity is enhanced through DWDM technology. The research results provide a scientific foundation aimed at improving the reliability and performance of optical communication and radio direction-finding systems.
