Integration of a Metropolitan Fiber Optic Ring for Telecommunications Network Convergence: A Feasibility and Impact Study in Mbanza-Ngungu

This study proposes the design and analysis of a metropolitan fiber optic ring for integrating the fragmented telecommunications networks in Mbanza-Ngungu, Democratic Republic of Congo. Faced with growing demand for high-speed connectivity and suboptimal existing infrastructure, the project aims to deploy a resilient, scalable, and open digital backbone. A field survey of 280 respondents (households, businesses, schools) reveals widespread dissatisfaction (≤23%) with current internet services but strong interest (62-70%) in fiber optics. The proposed architecture is based on a dual-feed ring using single-mode fiber with DWDM equipment, enabling operator interconnection, the creation of a local internet exchange point, and support for innovative services (telemedicine, online education, smart urban management). This neutral and scalable infrastructure represents a strategic lever for the city's digital transformation and its adaptation to smart city challenges.
