What should be done if there is any sign of water or moisture inside a cable?

When there are signs of water or moisture inside a cable, the appropriate action is to replace the cable. This is crucial because moisture within a cable can lead to a number of serious issues, including degradation of the cable itself, short circuits, and compromised signal quality. Once moisture penetrates a cable, it can cause corrosion and damage to the wiring and components that may not be visible without close inspection.

Replacing the cable ensures that the integrity of the system is maintained, as any residual moisture can lead to ongoing problems and potential failures in the network. While some may think drying it out or inspecting it further could be a solution, these methods often do not address the root problem and can leave the cable susceptible to future issues. Ignoring the moisture is not an option, as it can exacerbate the situation and lead to more severe repairs down the line. Therefore, replacing the cable is the safest and most effective course of action when moisture is detected.
