What is the purpose of buffering in fiber optic cables?

Buffering in fiber optic cables serves the essential purpose of providing protection against environmental factors and physical damage. The buffering material acts as a protective sheath that surrounds the optical fiber core, safeguarding it from moisture, dust, chemicals, and physical impacts that could potentially harm the delicate glass fibers inside. This additional layer is crucial in maintaining the integrity and performance of the fiber optic communication by preventing degradation over time due to external influences.

Furthermore, buffering helps to maintain the optical fiber's structural integrity during installation and regular use, ensuring that the signals transmitted through the fibers remain clear and uninterrupted. This is vital for maintaining the efficiency and reliability of data transmission in various environments, from industrial settings to residential installations.

While the other options might touch on aspects related to fiber optics, they do not accurately address the primary role of buffering in enhancing the physical robustness and durability of the cable system.
