Answer 2

$\huge\mathfrak{Answer}$

Optical fibres consists of things strands of long glass whose thickness is that of a human hair. These wires are arranged in bundles which are technically called Optical Fibre cables and are used to transmit data through light signals over long distance using the principle of total internal reflection. The data transfer rate in the faster among all the transmission media.

An optical fibre consists of the following parts

• Core : Core is the thin glass rod at the centre through which the light travels.

• Cladding : Cladding is the outer optical material surrounding the core that reflects the light back into the core.

• Buffer coating : It is the plastic coating that protects the cable from damage and moisture.
