Data Communication Through Fiber Optics Link

This trainer kit  is the base-line for every fiber optic laboratory. It demonstrates state-of-the-art concepts in fibre optic communications. It provides for easy experimentation and effectively bridges the gap between a leading-edge technology and currently available technical training tools. As the concepts demonstrated are no different from those encountered in real-life systems, it can provide significant insights, of direct relevance, to the student and practicing engineers alike.

The following experiments to be done :

  • Experiment No.1

To measure the Numerical Aperture (N.A) of the given fiber cable.

  • Experiment No.2
