Abstract

Indonesia has entered the stage of digital era where the trend of internet users as well as activity for online transactions has grown significant in the last 5 years. Meanwhile, the demographic population of Indonesia has shown major problem where the distribution of occupants are concentrated in main islands and villages or rural areas. This condition rises problem of connectivity as well as to provide equal information access to all citizen through out the islands. For this reason, government of Republic Indonesia has setup the Palapa Ring Network that is designed to connect all provinces and cities. However, the problem of connectivity still does exist since the Palapa Ring Network has a space or barrier for reaching the last mile access or users in the villages or rural areas. In concerning those problem, a scheme of optical relaying network that uses full-duplex of free-space optical (FSO) communications is proposed in this research as one of the solution to connect city and rural areas. Full-duplex of FSO implement two channels of wavelength division multiplexing (WDM) that capable carry 20 Gbps. The finding of the research is the length of optical propagation that is supported by two nodes transmission for each hop can be expanded into 4-6.25 Km where the performance of SNR is at the range of 42.92-33.179 dB and BER is at the range of 2.3×10-9-3.5×10-8
