The government and The House of Representatives of Indonesia have decided to move the capital city from Jakarta to Nusantara. Nusantara is the world's superhub and the driver of Indonesia's new economy, following its vision to create 4.3 - 4.8 million new jobs. The relocation of the capital will mean moving around 1.9 million people to the Nusantara. Thus, Nusantara requires high internet network connectivity with large bandwidth. This study proposes a fiber optic telecommunications network backbone design that connects the new capital Nusantara with Singapore and Jakarta via Pontianak. The proposed design for the connection from Nusantara to Pontianak is a land route, while from Pontianak to Singapore and Jakarta is a sea route. The design results show that the power loss and rise time values follow the standards, respectively 45 dB for power loss and 684 ps for the rise time. Therefore, the proposed network design is feasible to be implemented.
