What is an effective option for a broadband cable network to enhance its optical fiber resources?

Leasing spare fibers is an effective option for a broadband cable network to enhance its optical fiber resources because it allows the network to quickly increase its capacity without the need for significant capital investment or lengthy deployment times associated with new infrastructure. By leasing spare fibers from another provider, the network can make use of existing unused fibers, thereby extending service capabilities and improving overall network efficiency. This approach is particularly advantageous when there is a sudden increase in demand or a need for temporary solutions, as it provides flexibility and quick access to additional bandwidth.

In contrast, adding more connectors may introduce additional points of failure and attenuation, while using redundant pathways, although beneficial for reliability, may not directly increase the overall capacity. Investing in more equipment requires substantial financial resources and a more extended installation period, which may not address immediate demands for enhanced fiber resources.
