What is the main purpose of using protective tubing in fiber optics?

The primary purpose of using protective tubing in fiber optics is to keep the fiber safe from physical damage and moisture. Fiber optic cables are delicate and can be easily damaged by environmental factors, such as moisture, dust, or physical stress. The protective tubing functions as a barrier, safeguarding the internal fibers from external impacts that could lead to signal loss or complete failure of communication.

Additionally, the tubing prevents moisture ingress, which is crucial because water can cause a variety of issues, including corrosion of the optical fibers and diminished performance due to increased attenuation. The integrity of the protective tubing directly influences the reliability and longevity of the fiber optic system. Therefore, its role in protection against both physical and environmental hazards is vital to maintaining the network's overall performance and durability.
