Optical Fiber Kit

Item Code: SEA92

Working and Principle :

In order to understand the fundamental of optical fibers and analogue optical fiber communication, this kit has been designed. Wiring diagram for Fiber Optic Analogue Transmitter, Fiber Optic Analogue Receiver, Fiber Optic LED Driver and Optical Power Meter has been shown on the panel of kit.
In the present setup, eight experiment can be performed by using this trainer. The user can design a number of other interesting experiments and small projects based on the kit. Provided with detailed instruction manual.
