Fiber Optical Cable

FIBER OPTICAL CABLE

Fiber optical cable is a cable consisting of one or more thin flexible fibres with a glass core through which light signals can be sent with very little loss of strength.

Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with much lower attenuation compared to electrical cables.

 There are two main types of material used for optical fibers: 
  • glass 
  • plastic.
