Do non-conductive communications systems require surge protection?

To understand the requirements for surge protection in non-conductive communications systems, it's crucial to recognize the role of conductivity in surge events. Non-conductive materials are inherently less likely to allow electrical currents to flow through them, meaning that they do not conduct electricity in the same way metals do. Consequently, these systems are less susceptible to the direct effects of lightning strikes and power surges, which typically aim towards conductive pathways.

Non-conductive communications systems can still be affected by electromagnetic interference or induced currents from nearby lightning strikes; however, the level of risk is significantly lower compared to conductive systems. Many non-conductive systems, like certain fiber optic cables or radio-frequency systems, do not require the same level of surge protection as their conductive counterparts. In many practical applications, these systems can function without the need for additional surge protection, especially since the lack of conductivity minimizes the chance of surge damage.

This context supports the choice that non-conductive communications systems generally do not require surge protection under normal circumstances.
