Bandwidth capacity and high data rates improvement in Eastern Indonesia become an important aspects in empowering communities that is aimed to facilitating access to information in various sectors. The East Palapa Ring Package project was launched by the Ministry of Communication and Information to meet these needs. The design of optical fiber networks in East Nusa Tenggara Province was carried out in this study to support that project. This province is one of the area that has a high data rates needs especially for the security and tourism sector, because its territory is directly adjacent to other countries and has a high potential of tourism there. A total of 22 routes connecting districts / cities in East Nusa Tenggara were proposed by using Power Link Budget and Rise Time Analysis. From the results, it is known that the Power Loss and Dispersion Time in the proposed network do not exceed the permitted limits, which are 53 dBm and 233.33 ps respectively. Therefore, the proposed optical fiber network is in accordance with the expected and feasible targets to be carried out.
