What can be accomplished by converting to an underground installation during outside plant fiber-optic restorations?

The correct choice highlights the benefits of converting to an underground installation during outside plant fiber-optic restorations. When a conversion to underground is made, it can facilitate a more stable and protected path for the fiber-optic installation. Aerial installations are often subjected to environmental stresses such as wind, ice, and falling branches, which can lead to frequent outages. If a suitable underground path exists, implementing this change can prevent such frequent interruptions, thus improving the overall reliability of the network.

The option pointing to aerial span replacement accurately reflects the practical consideration of finding a more secure and long-lasting solution during restoration efforts. By leveraging existing underground pathways, operators can circumvent the challenges posed by aerial installations and reduce the risk of future damages and repairs, leading to enhanced service continuity.

In contrast, other choices suggest outcomes that do not align with the primary benefits of moving to an underground installation. Permanent fiber restoration implies that the issue will be fully resolved, but transitioning to underground mainly enhances reliability rather than guaranteeing permanence. While reduced repair costs might seem intuitive, the conversion often requires a significant initial investment that may not immediately translate to cost savings. Lastly, increased downtime for the restoration process contradicts the purpose of converting to underground; instead, it typically aims to minimize downtime by providing
