Abstract

The rapid expansion of mobile communication networks requires reliable, high-capacity, and resilient backhaul solutions, particularly in regions with limited fiber infrastructure. This paper presents a comparative performance evaluation of radio relay links (RRL) and fiber-optic communication lines (FOCL) deployed at mobile base stations using the NCTUns Network Simulator (version 6.0). A virtualized simulation environment was developed to model realistic mobile backhaul scenarios, including traffic queues, routing behavior, wireless channel fading, and error characteristics. Key performance indicators such as bit error rate (BER), signal-to-noise ratio (SNR), data transmission rate, and end-to-end latency were evaluated under identical network conditions with constant bit rate traffic. Simulation results indicate that FOCL significantly outperforms RRL, achieving BER values on the order of 10⁻⁹, stable SNR levels above 45 dB, data rates exceeding 100 Gbit/s, and average latency close to 1 ms. In contrast, RRL exhibits BER values around 10⁻⁵, SNR levels between 20 and 25 dB, and latency ranging from 5 to 20 ms, while offering advantages in rapid deployment and infrastructure flexibility. Based on these results, a hybrid FOCL/RRL backhaul architecture with a logic-based backup selection algorithm is proposed. The algorithm enables automatic switching between fiber-optic and radio relay links based on latency and link quality thresholds, thereby improving network resilience, availability, and service continuity.
