Question

write the advantages of optical fibre over twisted pair and coaxial cable. (who answer's the question correctly they will be marked as brainliest)​

Answer 1

Answer:

Optical fibre works on the principle of TIR ( total internal reflection ).

In TIR, the light rays rebound from the surface of the travelling medium without refraction ( The angle of incidence is greater than the critical angle ) , and the energy loss is almost zero, hence it is more preferred.
