Design and Analysis of an XGS-PON Technology for an Urban Area FTTH Network with Unidirectional and Bidirectional Transmission

FTTH is a network technology from the head office to the user area using a fiber optic cable. Urban areas are strategic areas for deploying FTTH networks. In 2022, Indonesia had an average data rate of 16.52 Mbps. With an increasing population, greater bandwidth is needed. Therefore, this research was conducted to design an FTTH network based on XGS-PON (10 Gigabit Symmetrical-Passive Optical Network) technology. This research will design 2 sets of XGS-PON technologies, unidirectional and bidirectional, to find the best performance. Variations of the fiber cable length in the XGS-PON circuit are 1:256, 1:128, and 1:64 splitter. The research results show that the transmission power and splitter ratio affect the result of the BER value, the obtained power, and the attenuation class. Furthermore, the results show that both unidirectional and bidirectional circuits have decent performance at fiber cable lengths specified in the ITU-T G.9807.1 standard. Based on the BER obtained on unidirectional and bidirectional circuits, it can be seen that XGS-PON technology performs better on bidirectional circuits.
