Besides protection, what essential functions must the coating on an optical fiber cable perform?

The coating on an optical fiber cable plays a critical role in ensuring the functionality and reliability of the fiber. One essential function is its compatibility with cable gels and its ability to adhere effectively to the glass cladding. This ensures that the protective layers surrounding the fiber can maintain their integrity during installation, thereby minimizing the risk of damage to the delicate glass core, which is pivotal for signal transmission.

Adhering properly to the glass cladding helps secure the core within the cable structure, preventing movement that could lead to micro-bending or other forms of physical stress which can negatively affect performance. Additionally, compatibility with any cable gels used in the construction aids in providing further protection from moisture and debris, which could impair the optical signals transmitted through the fiber.

While other options touch on aspects of fiber cable functionality, they do not address the coating’s pivotal role in adhering to the cladding and fitting with protective gels. This highlights why the correct answer centers on adherence and compatibility, as these factors are essential to maintaining the optical integrity and durability of the fiber optic cable.
