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.
