Fibre optic cables- Very important for prelims
Why?- Because digital India dream relies on internet connectivity and penetration- this depends on fibre optic cables
Imp Points to note: for the rest, read the highlights
1. Quantum Optics and Fibre Optics: They can be used to send anything that can be encoded as digital information across large distances at the speed of light.
2. Technical point : The reflective index of the core of an optical fibre determines how fast light can travel in it. When a beam travels in the core, the reflection at the interface ensures that the light remains within the core.They work by transmitting light within the core of the cable, which is made of glass or plastic. Total internal reflection ensures that light stays within the cable, allowing for long-distance and high-speed data transmission.
