How does environmental temperature affect fiber optic cables?

Environmental temperature has a significant impact on the physical durability of fiber optic cables. Fiber optic cables are composed of materials like glass and polymers, both of which can be sensitive to temperature changes. In extreme temperatures, these materials may expand or contract, potentially leading to physical stress, which could affect the integrity of the fiber.

For instance, at high temperatures, the risk of softening or deformation may increase, while at low temperatures, materials can become brittle and more susceptible to fractures. These physical changes can lead to micro-bends or macro-bends within the fiber, which could ultimately hinder light transmission and degrade the overall performance of the cable.

Understanding the relationship between temperature and durability helps installers in selecting the appropriate cable type for specific environments, ensuring that installations can withstand varying climatic conditions without compromising performance.
