Optical fiber coatings/buffers play an important role in protecting the fiber from its intended environment. However, the integrity and performance of these cables are highly susceptible to various environmental and physical factors. Therefore. Optical fiber cables from SICK consist of three main components: a sensor head, a fiber, and a sheath. Without robust protection, fiber optic cables are susceptible to environmental influences such as moisture, temperature fluctuations, and ultraviolet (UV) radiation, which can all lead to premature aging and performance degradation. Secondly, optical fibers or fiber bundles are contained within a tube – or sheath – either a a fiber optic cable or as a sensor.
