Optical Fibers are based on Total Internal Reflection.
The phenomenon in which the angle of incidence is more than the critical angle is known as total internal reflection.
Characteristics of optical fibre:
- The bandwidth of the optical fibre is large with a frequency of 2 × 1014 Hz.
- The transmission losses in an optical fibre are near to 0.1db/km.
- They are flexible with high tensile strength.
- Communication using optical fibres are free from electromagnetic interference.
