LINK-C is a Basic Fiber Optic Trainer Kit designed to experimentally measure the speed of light. This kit utilizes an oscilloscope to monitor a light pulse in its passage between a transmitter and a receiver, coupled with fiber optic cable. At the receiver, the oscilloscope displays the phase delay and basis for the calculations which will determine the speed of light through the fiber. A 20MHz dual trace oscilloscope (not included in the kit) is required to make the measurements.

Link-C can further be used as an Analog Link to study the fundamentals of fiber optics, including characteristics of fiber optic cable & fiber optic components.
Facility is provided in Link-C to study the effect of EMI interference on optical fiber cable. It can be noticed that there is absolutely no effect of EMI interference on data transmitted through optical fiber cable. To enable students to understand this effect, it is demonstrated in this kit, that EMI interference is observed when medium of transmission of data is copper cable.
Link-C can also be used for Analog communication for a small distance. An exhaustive manual is provided with the kit. This manual contains excellent documentation on each & every experiment, data sheets of components used & circuit diagram of the complete kit.
