Optical fiber is a cylindrical dielectric waveguide that transmits light along its axis by the process of total internal reflection. The fiber consists of a core surrounded by a cladding layer. To confine the optical signal in the core, the refractive index of the core must be greater than that of the cladding.
The light source used for optical fiber communication can either be a light-emitting diode (LED) or a laser, usually in IR range. Fiber optic experiments described in this section utilize red diode lasers and LEDs for giving visual experience of fiber optic transmission.
Objective of our Fiber Optics Kit is to impart the basic knowledge in principles and applications of fiber optics. It is made up of a number of laboratory experiments aimed to give hands on experience in understanding the basic concepts. The experiments help to acquire laboratory techniques which can be used for the characterization of important fibre parameters.
