The core of the fiber optic cable is made of very pure and clear material for the easy reflection of light. Mostly glass is used as the core of the fiber optic cable. However plastic may also be used as the core for short distance transmission. The glass of the fiber optic cable is almost always made from pure silica along with other materials like chalcogenide, fluorozirconate and fluoroaluminate which are suitable for longer wavelength infrared applications.

Advantages:

  • Offers high speed & large carrying capacity.
  • Smaller maintenance costs.
  • Provides greater resistance to electromagnetic noise from motors, radios and the neighboring cables, especially power cables.
  • Use  light as a transmission medium.
  • Suitable for carrying transmission at both long and short distances.
