Railways airport is one of the modes of public transportation, with routes starting from Manggarai Station to the Soekarno-Hatta Station. One of the required communication infrastructures is an optical fiber. It is essential to design and analyze the installation of optical fiber through the route of the railway airport to improve the communication system between the station and the central office. Moreover, installing optical fiber can improve network connectivity, benefiting passengers and the commuter line. This paper discusses a proposed design and analysis of optical fiber network deployment on the Soekarno Hatta Airport railroad. The power link budget illustrates the overall optical power losses calculated for every line between Manggarai Station and Soekarno-Hatta stations. The losses between each station are 17.01 dB 19.09 dB, resulting in a system rise time for each station between 98.336 - 259.262 ps. The proposed network design is feasible to provide an appropriate performance.
