What does protective silicone coating do in a fiber optic cable?

The protective silicone coating in a fiber optic cable serves a crucial function by safeguarding the inner components from environmental factors. This coating acts as a shield against moisture, temperature variations, chemicals, and physical abrasion, ensuring that the sensitive optical fibers remain intact and operational. By protecting these components, the silicone coating helps maintain the integrity of the fiber, which is essential for reliable data transmission over the cable's lifespan. This protective feature is vital in various environments where fiber optic cables may be exposed to harsh conditions, making the silicone coating an important aspect of their design and functionality.
