What is the role of buffers in fiber optic cables?

Buffers in fiber optic cables serve a critical protective role. They are designed to shield the delicate fiber core, which transmits light signals, from physical damage that could occur during installation or handling. This includes safeguarding against bending, crushing, or other mechanical stresses that could impair signal integrity. Additionally, buffers provide a layer of protection against environmental factors such as moisture or chemicals that could degrade the optical fibers over time.

Understanding the importance of buffers is key to recognizing how they contribute to the overall reliability and longevity of fiber optic communication systems. By ensuring that the fiber core remains intact and undamaged, buffers facilitate consistent transmission of optical signals, which is essential for effective communication.
