Abstract
For next-generation passive optical networks (NG-PON), this study investigates the technological and financial viability of centralized laser source designs, commonly known as optical distribution networks (ODNs). Conventional ODNs are expensive because they use separate lasers at each optical line terminal (OLT). This study suggests a centralized laser source architecture in which several OLTs are fed by a single high-power laser via passive optical splitters. A centralized laser source with a minimum output power of 10 mW can meet the required network performance, with quality factors exceeding six and low bit error rates, according to simulations done for a 6-OLT deployment in Chandigarh, India. Centralized laser ODNs are an appealing option for large-scale deployments, as cost analysis shows initial savings of roughly 63 % when compared to traditional configurations. The proposed system also demonstrates dependability, scalability, and compatibility with emerging technologies, making it ideal for future network expansions.
