What is the purpose of cladding in fiber-optic cables?

  • Cable grounding
  • Noise cancellation
  • Prevention of light loss
  • EMI protection

Explanation: Cladding is the glass that surrounds the core and acts as a mirror. The light pulses propagate down the core, while the cladding reflects the light pulses. This keeps the light pulses contained in the fiber core in a phenomenon known as total internal reflection.
