The railway sector is a major user of advanced technologies, including fiber optics, to ensure the safety and efficiency of railway operations.

One of the main uses of optical fiber in the railway sector is the transmission of data between stations and centralized control systems. Optical fiber allows large amounts of data to be transferred at high speed, ensuring precise and timely management and control of railway operations. Optical fiber also offers greater reliability than other communication technologies, ensuring the continuity of railway operations even in the event of technical problems.

Furthermore, optical fiber is used for the surveillance of railway infrastructures. Fiber optic-based sensors can detect the presence of any structural or safety problems, such as vibrations of the rails, changes in temperature or the presence of people or objects on the railway line. These sensors make it possible to constantly monitor the status of railway infrastructures, ensuring greater safety and reliability of operations.

Furthermore, optical fiber is also used for the control of safety systems on board trains. Onboard safety systems, such as automatic braking systems, use optical fiber to transmit control signals between the train and the central control system, ensuring greater safety and reliability of railway operations.

Finally, optical fiber is also used to enhance the passenger experience on board trains. For example, optical fiber makes it possible to provide high-speed Internet connections to passengers, allowing them to surf the web, watch movies or work while on the road.
