How does temperature affect fiber optic cables?

Temperature plays a significant role in the performance and longevity of fiber optic cables. While fiber optic cables are designed to withstand various environmental conditions, extreme temperatures—both high and low—can lead to physical damage or performance degradation. High temperatures can cause the materials within the cable, such as the protective coatings or the core and cladding, to soften or deform, resulting in issues like signal attenuation, increased loss, or even complete failure in severe cases.

Conversely, low temperatures can make certain materials brittle, increasing the risk of cracking or breaking when the cables are installed or handled. Such damage can compromise the integrity of the fiber optic system. Therefore, understanding the effects of temperature on fiber optic cables is crucial for ensuring reliable performance and planning for appropriate installation and maintenance conditions.
