Fragmented Optical Distribution Point (ODP), fiber-route, customer, and fault records limit a shared operational view of Fiber to the Home (FTTH) incidents. Objective: This study developed a Web Geographic Information System (Web-GIS) that integrates spatial FTTH assets with a transparent two-stage fault-priority rule. Methods: Applied research used observation from 11 January to 11 February 2026, semi-structured interviews with two technicians, sequential system development, and a dataset of 40 ODPs, 6 routes, 150 customers, and 30 fault reports. Evaluation separated ten functional scenarios, a custom ten-item usability questionnaire completed by four internal role-based users, two sampled coordinate comparisons, hosted-page performance observations, and four simulated scoring cases. Results: All ten scenarios produced the expected outputs. The four users contributed 194 of 200 questionnaire points (97%), reported descriptively because the instrument and sample were limited. Two sampled ODP coordinates agreed with retained Samsung smartphone map readings. Seven non-map operations completed in less than one second, while the network map required 10.67 s. Manual and application calculations agreed for all four simulated scoring cases. Conclusion: The application integrated selected spatial and operational records, implemented the approved role-based workflow, and reproducibly executed the predefined scoring rules. It is designed to facilitate fault tracing, but faster tracing, decision validity, and organizational impact were not measured.
