Which topology is primarily used in fiber-to-the-user (FTTx) networks that requires enhanced fiber color code management?

In fiber-to-the-user (FTTx) networks, the point-to-multipoint (P2MP) topology is commonly employed due to its efficient use of fiber as it enables a single fiber strand to serve multiple users or endpoints. This topology is particularly advantageous in scenarios where scalability and cost-effectiveness are critical, allowing service providers to distribute fiber connections to many users from a single central point—often referred to as a splitter.

Enhanced fiber color code management is essential here because multiple fibers must be distinctly identified and managed as they converge at splitters and other distribution points. In P2MP configurations, proper identification of fiber strands involves using color coding, which ensures that technicians can easily trace and manage individual fiber connections without confusion, minimizing errors during installation and maintenance.

This approach contrasts with other topologies where the distribution of fiber might not be as efficient or scalable. In a star topology, while there can be some level of fiber color management, each connection involves running a dedicated fiber to a central point, which can be more resource-intensive. Bus and ring topologies are less common in FTTx networks due to their limitations in easily managing multiple user connections and the complexity involved when adding or removing endpoints. Thus, the point-to-multipoint topology
