The optical fibers used in fiber optics are made of:

by

A. Plastic
B. Glass
C. Copper Particles
D. None of these

  1. Optical fibers are thin, flexible strands made mostly of glass or plastic that carry light signals for fast communication over long distances.
  2. They work by guiding light through their core using a process called total internal reflection, which keeps the light inside the fiber without loss.
  3. Optical fibers are used in internet, telephone, and medical devices because they provide faster data transfer, are immune to electrical interference, and can carry large amounts of information.

🧠 Explanation:

Optical fibers, used in fiber optics, are made of glass, transmitting light signals for high-speed communication. Their thin, flexible strands enable internet, phone, and data networks with minimal signal loss. Glass’s clarity and durability make it ideal for long-distance transmission. Studying optical fibers highlights their role in telecommunications and technology, a key topic in engineering and IT, driving modern connectivity and shaping global communication infrastructure for faster, reliable data transfer.
