What is a potential consequence of excessive moisture exposure in fiber optics?

Excessive moisture exposure in fiber optics can lead to the corrosion of fiber optic connectors. Connectors are critical components that allow for the mating of fiber optic cables and facilitate the transfer of light signals. When moisture infiltrates these connectors, it can initiate chemical reactions that degrade materials used in the connectors, leading to corrosion. This corrosion can result in increased signal loss and reduced performance, ultimately affecting the reliability of the fiber optic communication system.

Other potential outcomes of excessive moisture exposure could include the degradation of the optical fibers themselves, though this is not specifically mentioned in the options. The correct choice highlights the specific detrimental effect that moisture can have on connectors, which are vital for maintaining signal integrity.
