What is the ideal way for a broadband cable network designer to plan the replacement of coaxial cable with fiber-optic cable?

Using the existing coaxial network infrastructure is the ideal way for a broadband cable network designer to plan the replacement of coaxial cable with fiber-optic cable. This approach takes advantage of the pre-existing physical pathways and structures that have already been established.

By utilizing the existing coaxial network infrastructure, the designer can significantly reduce costs and time associated with the deployment of fiber-optic cables. The coaxial cables can serve as a guide for the new fiber, minimizing the need for extensive new installations or additional excavation. This method enhances efficiency and practicality by leveraging current resources rather than starting from scratch.

Additionally, this approach can also facilitate a smoother transition for users, minimizing service disruption. Network reliability can be maintained during the upgrade process because parts of the existing network can remain operational while the fiber-optic cables are being installed. It allows for a phased approach to the transition, ensuring that the network can still provide service while improvements are being made.

Context to other options reveals that installing new pathways could lead to excessive costs and time delays, creating complications in network management. Implementing wireless connections may not meet the necessary bandwidth or reliability that fiber offers compared to coaxial, especially for high-demand users. Creating a completely new design would also be overly ambitious and resource-intensive
