What is one reason broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once?

Broadband cable operators install fiber-optic cable in stages primarily to prevent service disruptions. By implementing a phased approach, operators can upgrade parts of their network incrementally while maintaining service to customers. This method allows for the careful planning and execution of the installation process, minimizing the risk of widespread outages that could occur if the entire infrastructure were replaced simultaneously. When fiber is installed gradually, operators can monitor the performance of the new system in real-time, ensuring that each segment is functioning properly before moving on to the next phase. This approach not only helps maintain customer satisfaction and service reliability but also enables companies to address any potential issues that arise during installation without affecting the entire network. This allows for a smoother transition to the improved fiber-optic infrastructure.
