Özet

In this study, signalling in railway transportation systems are considered and their working mechanism is investigated. The applications and structures of the communications systems in railway transportation industry where high speed communications are essential for safety are assessed, within the framework of the broad band and high data transmission rates of optical fibers due to their operation in THz level. In this study, an optical communication system, where temperature, pressure, air condition, door sensor, emergency switch and routing signals reach a central control unit after passing through the converters of the wavelength division multiplexing system, WDM, and elements where pulse code modulation, PCM, is applied, is analysed. The system is modelled with OptiSystem 7.0 simulation program. © 2012 IEEE.
