Today, huge amounts of data are transmitted around the world through the high capacity of the optical telecommunication networks. In railways, optical transmission networks play an important role in transmitting vital rail data too. Improving the reliability of telecommunication infrastructures is essential to increase productivity, maintain traffic safety and reduce maintenance costs. In this paper, first the reliability of the optical transmission telecommunication network has been modeled and calculated analytically through RBD method and then its results have been approved through Monte Carlo simulation. Due to the importance of the optical transmission network in railway safety, the probability of optical transmission network outages and the Mean Time between Failure (MTBF) for 3 years have been calculated and simulated. A case study for this research was performed by using the real breakdown statistics of the network based on the optical telecommunications of the high-traffic railway area in "Azerbaijan District”, one of Iranian Railways network in north-west of Iran.
