Explain about the number of modes in the optical fibres.
Mode in the optical fibres:
A mode is a path occupied by a ray of light through an optical fibre. This is a mathematical concept of describing the propagation of light waves into an optical fibre. The number of modes of propagation into a fibre depends onto the diameter of the fibre core. Generally, narrower of the fibre core lesser is the number of modes of propagation. Therefore on the basis of number of modes, fibres are categorized as:
a. Single-mode fibre
b. Multimode fibre
