Railways refer to optical cables used for the control of railway networks and optical communication, supporting the power supply, signaling systems, data communication, and safety systems necessary for the operation of electric trains. High-voltage power cables play a crucial role in supplying electricity to electric trains, while signaling cables ensure the safety of train operations. Additionally, optical cables for data communication enhance the efficiency of railway operations and enable real-time information transmission. This infrastructure strengthens the efficiency and safety of railway operations, playing a key role in various railway systems, from public transportation to long-distance freight transport.
