Answer:- Fusion splicing is the act of joining two optical fibres end to end using heat.The goal is to fuse the two fibres together in such a way that light passing through the fibres is not scattered or reflected back by the splice, and so that the splice and the region surrounding it are almost as strong as the virgin fibre itself.

Answer:- Fibre optics is a technology in which signals are converted from electrical into optical signals, transmitted through a thin glass fibre and reconverted into electrical signals.

Answer:- A ray that propagates through the fibre undergoing total internal reflection is called meridional ray.
