In the era of digitization, increasing reliable broadband internet connection with a large capacity is important. There is still no Terrestrial network in the Jakarta-Bandung region to support fast broadband connectivity. The development of the Jakarta-Bandung High-Speed Train railway can be used to convey the development of a backbone fiber-optic network, which can save money and time compared to self-deployed projects. This paper offers a design and analysis for a fiber optic backbone deployment. The architecture offered utilizes four stations as a place to place the transmitter, two repeaters, and receivers. Several technical parameters are determined, then analyzed using the Link power budget, Rise Time Budget, and Bit Error Rate. The Link Power Budget Analysis shows that the system's distance ranges from 116.57 Km to 120 Km. From the Rise Time Budget Analysis, the maximum rise time of the system ranges from 58.171 ps to 66.692 ps. The Bit Error Rate Analysis shows that the BER of the system design is 6.71 x 10. Thus, the system design can be implemented if these results are compared with the parameters to be achieved.
