What is a design option for a broadband cable network to maximize the use of its optical fiber resources?

Leasing spare fibers is a strategic design option to maximize the use of optical fiber resources in a broadband cable network. This approach allows network operators to utilize available fiber capacity without the need for significant infrastructure investments or upgrades. By leasing fibers, operators can effectively expand their service offerings and coverage, accommodating more customers and higher bandwidth demands. This effectively leverages existing resources and enhances network efficiency, ensuring that the operator can meet growing data needs without the delays and costs associated with building new physical infrastructure.

In contrast, upgrading all existing cables may be costly and time-consuming, potentially leading to service interruptions and requiring significant capital investment. Reducing service coverage would limit the number of customers and overall network effectiveness, directly undermining the goal of maximizing resources. Increasing amplifier stations may improve signal strength and quality, but it does not address the underlying issue of fiber resource allocation and could also lead to increased operational complexity and costs. Thus, leasing spare fibers offers a more efficient and scalable approach to optimize the existing optical fiber infrastructure.
