How does heat affects the fiber optic transmission?

Heat can adversely affect fiber optic transmission by increasing attenuation, which reduces signal strength. Elevated temperatures can cause changes in the optical properties of the fiber material, leading to greater scattering and absorption of light. Additionally, excessive heat can damage the protective coatings and connectors, potentially resulting in signal loss or complete failure of the transmission system. Maintaining optimal temperature conditions is crucial for reliable fiber optic performance.
