Reliable communication between railway stations and level crossing officers is essential for ensuring train safety and operational efficiency. Conventional mechanical bell systems have limited communication reliability and require frequent maintenance. This study proposes the design and implementation of a fiber optic–based officer reminder system to provide real-time notifications of train arrivals and departures in PT Kereta Api Indonesia (PT KAI) Operational Area 8 Surabaya. The proposed system integrates Arduino Uno controllers with Ethernet Shields, fiber optic media converters, and audio-visual signaling modules to establish communication between Lamongan Station, Surabayan Station, and connected level crossing posts (JPL). System performance was evaluated through field implementation using Quality of Service (QoS) parameters measured with Wireshark. The experimental results showed an average delay of 4.21 ms, jitter of 4.59 ms, packet loss of 0%, and throughput of 0.844 kbps. These results demonstrate that the proposed system provides stable, reliable, and low-latency communication suitable for railway signaling applications. The implementation of optical fiber communication improves notification accuracy, enhances operational coordination between stations and level crossing officers, and offers a more reliable alternative to conventional mechanical bell systems for supporting safe and efficient railway operations.
