<![CDATA[This study addresses the absence of MyRepublic FTTH services in Taman Asri 8 Housing, Padang City, which creates a need for an appropriate fiber optic access network design to serve the 212 existing housing units. This research aims to design and evaluate a Fiber To The Home (FTTH) network based on Gigabit Passive Optical Network (GPON) technology using the Network Planning Process (NPP) method, consisting of requirement analysis, desktop survey, field survey, network design, and feasibility analysis. The network layout was developed using AutoCAD, while its performance was evaluated through Link Power Budget (LPB) and Rise Time Budget (RTB) calculations and OptiSystem simulations. The evaluation considered received optical power, BER, and Q-factor parameters. The results show that the proposed network can serve 212 homepasses through one Optical Distribution Cabinet (ODC) and 15 Optical Distribution Points (ODPs). The calculated received optical power for the nearest, middle, and farthest paths is −19.817 dBm, −20.004 dBm, and −20.185 dBm, respectively, while the simulated received power ranges from −19.181 dBm to −19.549 dBm. The rise time ranges from 0.2500 ns to 0.2506 ns, the BER ranges from 4.27181 × 10⁻¹⁷ to 2.81757 × 10⁻¹³, and the Q-factor ranges from 7.20846 to 8.32338. These results satisfy the adopted performance criteria, namely received power above the ONT sensitivity limit of −28 dBm, rise time below 0.292 ns, BER below 10⁻⁹, and Q-factor above 6, in accordance with the GPON performance evaluation framework. These findings indicate that the proposed GPON-based FTTH network is technically feasible for implementation in Taman Asri 8 Housing, Padang City.]]>
