Why do broadband cable operators opt to install fiber-optic cable in stages?

Broadband cable operators often choose to install fiber-optic cable in stages to avoid service disruptions. By implementing the upgrade process incrementally, operators can manage and mitigate potential interruptions to existing services. This approach allows them to maintain reliable service for customers while progressively enhancing the network's capabilities. Phased installations enable technicians to test and optimize the new infrastructure before fully committing to it across the entire network, ensuring that any issues can be addressed without affecting all users simultaneously.

While other choices may contain elements of truth, the primary goal is to maintain service continuity for customers during the upgrade process. Reducing initial installation costs and enhancing existing infrastructure gradually are also considerations but do not directly address the immediate concern of service availability during the transition. Upgrading the entire network at once would likely lead to significant disruptions, which the staged approach actively seeks to avoid.
