High humidity conditions do not significantly contribute to signal degradation in fiber optics. The primary factors impacting optical signal quality are related to the physical properties and handling of the fiber itself. Connector losses occur when light is not efficiently transmitted through fiber optic connectors, often due to misalignment, dirt, or damage. Splicing losses arise when two fiber segments are joined, and any misalignment or imperfections can cause light to be lost at the joint. Attenuation refers to the inherent loss of signal strength as light travels through the fiber, largely due to scattering and absorption within the fiber material.

In contrast, while high humidity might cause issues in other types of communication systems, fiber optics are largely unaffected by humidity levels, as the medium for signal transmission—light—does not rely on air quality. This makes high humidity not a direct contributor to signal degradation in fiber optic systems.
