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 for a broadband cable network seeking to maximize its optical fiber resources. By leasing spare fibers, the network can effectively expand its capacity without the substantial investment and time associated with laying new fiber infrastructure. This approach allows for a more efficient use of existing resources, enabling network operators to meet rising demand and serve customers in areas where increasing bandwidth is critical.

Leasing fiber can provide flexibility in service offerings, allowing operators to scale their operations according to market needs while maintaining control over costs. This is particularly advantageous in competitive markets where the demand for high-speed internet continues to grow rapidly.

In contrast, the other options may not contribute effectively to optimizing fiber usage. Installing more amplifiers can enhance signal strength, but it does not increase the amount of data that can be transmitted through existing fibers. Utilizing copper cables is generally less efficient for broadband services compared to optical fiber, which is designed to handle high data rates over long distances. Reducing service areas might limit access for customers and does not inherently maximize fiber use, as it could potentially underutilize available infrastructure.
