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

Opting for the existing coaxial cable network infrastructure is an efficient approach for a broadband cable network designer planning to replace coaxial cable with fiber-optic cables. This choice minimizes disruption and capitalizes on the already established layout of the network, allowing for a more seamless transition to fiber optics. By utilizing existing conduits, poles, or even duct systems where coaxial cables are currently deployed, the designer can cut down on installation costs and time significantly, making the process more economical.

This method also enables quicker deployment of fiber, as installing new infrastructure or dropping ducts into the ground can be labor-intensive and time-consuming. While maintaining the existing framework is a smart way to integrate new technologies, other strategies such as installing new underground ducts would require significant additional investment and resource allocation, which may not be practical for a transition aimed at improving efficiency.
