An optical fibre is based on:

The main reason of attenuation in optical fibre is :

Cotyledons are also called-

Advantages of optical fiber communications over two wire transmission line or co - axial cable transmission are

Assertion: Optical fibre has thin glass core coated by glass of small refractive index and is used to send light signals.

Reason: All the rays of light entering the fibre are totally reflected even at very small angles of incidence.
