The National Electrical Safety Code (NESC) primarily provides guidelines to ensure that utility infrastructure is designed and maintained in a manner that minimizes risks to the public and utility workers. Regarding fiber-optic cable networks, the NESC outlines minimum safety clearances that must be maintained between different conductors. This includes maintaining appropriate distances to prevent electrical hazards and ensure safe operation of both overhead and underground facilities.

Maintaining these minimum safety clearances is crucial as it helps prevent issues such as electrical arcing, interference, and facilitates safe access for maintenance and repair. By adhering to these guidelines, utilities can enhance safety for both the public and employees working with or around these installations.

The other options do not represent the primary focus of the NESC in relation to fiber-optic cables. For example, while installation techniques or specific types of connectors are important aspects of fiber-optic deployment, they are not primarily addressed by the NESC, which is more concentrated on safety and clearance standards rather than installation methodology or equipment specifications.
