What is the primary use of an optical fiber?

• A. To absorb light
• B. To share images through a lens system
• C. To transmit light signals
• D. To create reflections for visualization

Answer: (C)

The primary use of an optical fiber is to transmit light signals. Optical fibers are thin strands of glass or plastic that use the principle of total internal reflection to carry light over distances. When light enters the fiber at a certain angle, it reflects off the internal surfaces, allowing the light to travel through the fiber with minimal loss. This capability is essential in telecommunications, where data is transmitted in the form of light signals. The efficiency of optical fibers makes them ideal for long-distance communication, as they can carry large amounts of data rapidly and without the interference commonly encountered in traditional electrical signals. Furthermore, they are widely used in applications such as internet connections, medical instruments, and various imaging technologies, all leveraging their ability to transmit light effectively.
