LINK-D is a fiber optic trainer kit designed to learn physics of fiber optics including fiber preparation, connectorisation, coupling of two fibers, light travelling around corners in an optical fiber, colour light travelling down an optical fiber, photodiode detecting light, LED output as a function of current, adjusting coupling efficiency of the photodiode, transmission of light between two fiber, transmission through a gap between fibers, fiber optic transmission sensor, reflection sensor, all kinds of losses like connector loss, bending loss, coupling loss etc.
Also we can perform analog links, digital links and voice link. Ample number of experiments can be performed with this by referring to the exhaustive manuals provided with the kit. This manual contains excellent documentation on each & every experiments, data sheets of optical components used & circuit diagram of the complete kit.
